Ae86 Fuel Tank Into An Ae71...?

[Victim]

Yo homiez!

 

I hate fuel systems. I now smell of petrol. The only plus side of this whole operation is that the AE71 has a drain plug in the fuel tank, which means no siphoning for me!

 

I'll cut to the chase:

 

Trying to set up my AE71's 4AGE fuel system. I opted for the in-tank pump setup, not the external VL lifter + sender type setup, because i couldn't be bothered to deal with the noise, and to have to mount more things in the boot / under the car etc.

 

I mistakenly believed that the EFI pump from an AE82 would fit into my AE71's hole... WRONG! If you're reading this and thinking this is the go, IT ISN'T! Look at images from the two. The AE82's pump mounting plate has six screws. The AE71's has five. Fail @ life by me, the AE71's hole never had to be big enough to deal with a pump!

 

Anyways, i've been offered an AE86 ADM tank on the cheap, so i'm thinking that it might be worth it to create my own "JDM" type setup, i.e. the ADM tank with an in-tank pump, but i was wondering how much modification to the tank itself would be required?

 

I've read that the filler neck needs to be altered... How? And is there anything else needed to shoehorn that homie in?

 

I've tried searching on the e-webz... no luck.

 

THANKS HEAPS! E-beers all 'round.

The pump will fit through the hole from memory, but you still wont have baffles inside, unless you want to open it up, or copy Beerheads idea and fit a commodoore intank pump and baffle setup that drops in from the top.

 

Like I said you want atank from an Rt142 Corona or JDM AE86.

 

You can do under car surge tanks.

[Victim]

Yeah i did catch your reply to my last thread, much obliged sir...

 

Unfortunately so, but the only reason i need to go for the ae86 tank is because i've got the wrong pump for the wrong tank, so something needs to change, i.e. i need to get a different pump setup (something smaller, or go the VL route...) or change the tank that has a large enough hole to accept the pump down through the hole.

 

So i understand that it's not the best solution because i'm still stuck with a tank that has no baffling, but to be honest, my build is on a tight timeframe and i'm just looking at getting it going first, then overcoming any obstacles as they arise, e.g. surge. I will presumably add in an under-car surge tank later to overcome this problem.

 

The only problem with acquiring those tanks is i'm assuming the corona one might be difficult to source, and JDM one's are expensive as all hell. And basically, i can get access to an ADM one tonight, which follows on from the fact i've got minimal time to work with haha.

 

What is Beerhead's idea? I tried to do a member search, but had no luck...

If beerhead wants to share his idea he will.

 

Coronas arent hard to find, try looking before telling me its hard.

 

You really wont want to pull the tank out again once its running, and its seriously dangerous to get fuel surge.

 

Do it once, do it properly.

[Victim]

Well... sorry. I was just asking? I was merely curious as to if he had some kind of thread for this "idea" you speak of, and as i have no idea who beerhead is, i thought i'd ask you and / or search for him. Considering you brought up this "idea", i didn't think it was off limits to ask. Apparently i was wrong.

 

And as for them being hard to find, no, they are not. Possibly not the best choice of words. I'm sure i could go and find one now if i chose to, but as i mentioned earlier, i am pressed for time? And i can get an ADM tank tonight? My simple question was, what is needed to make an AE86 tank fit.

 

And i am aware of fuel surge being un-beneficial, i never stated that i believed it was a positive aspect of engine management to starve it of fuel. Considering it's a daily driver and to prevent surge you just make sure you have an adequate level of fuel in the tank and don't punt it around corners when you've got 1/8th of a tank left, i believe i can live with it. And / or add a surge tank now, if i can find one i can grab in the next couple of days.

 

If your main concern is i'm going to get surge from using an AE86 ADM tank, then the fix would be to include a surge tank. Simple.

 

I don't understand why you jump down my throat and criticise me for "not doing it properly" when the fix is simple, and i've clearly stated that all i want to know is how to shoehorn in an AE86 ADM tank into an AE71. Jesus.

 

 

 

If anyone else has some input as to what is required, feel free to hit me. All input appreciated.

[beerhead]

ADM AE86 and AE71 tanks are basically the same thing, possibly the filler caps are screw in for the AE86 though. Not an upgrade, no baffles in the ADM tank. Will bolt straight up though.

 

What LRS was talking about was the VT onwards commo intank surge tank being fitted to the stock KE70 tank. Surge tank You'll see it down the list with in those pics. Needs a metal ring laser cut and brazed to the tank, and custom gasket too.

 

The reason I'm going down this path is to not require 2 pumps or an external tank. The fuel pump has 2 in's and out's and I won't have to put up with the drone of a rattler in the boot.

I can see you didnt appreciate my input.

 

Ive never met a person on this forum with a more apt username. Why your'e the victim of my evil blunt, second time around answers, and didnt you get a bit excited.

 

The reason I was blunt is you asked basically the same questions twice, in two threads over a single week, and despite getting answers in the first one, you made another thread to ask further related questions? Bear in mind youve disregarded everything people have told you to do from the benefit of their experience, and you asked.

 

This attempted smart arse crap youv'e written is completely offensive, especially considering I'm encouraging you to do a safer job on your car. This effort to over-explain yourself in a sarcastic fashion is not appropriate. Pull your head in. If you keep this crap up you won't be on Rollaclub for long. Theres a wiki on this topic as shown above, and theres a whole 'nother one about setting up fuel systems with surge tanks.

 

:)

 

FYI, I have done exactly what you are attempting. I'm telling you do it with an efi tank. Ive seen people go through this before, and once the tanks in people rarely if ever will pull it out. If you are going to fit a surge tank later you can fit a little lift pump inside your ae71 tank, no need to get the ae86 tank at all. You can make a surge setup work with what you already have. But hey, if the tanks from an ae86, your car will drift better right? The you can tell people its got an ae86 tank, cause that would be the only point to the swap, other than having a filler that doesnt quite work. Id prefer a neat filler area, if I were just going to retro fit a lift pump in the tank to feed a surge tank later.

 

But hey, you already seem to have made all your decisions, so with that revelation, do whatever you want cause I don't care anymore, and don't patronise us with more questions, since you don't care what people say.

 

Its reassuring for me to know that you will never, ever have a rush of blood and attack a corner with full force with a low tank, since you are obviously infallible and incapable of forgetting anything or making an error.

RT 142 corona 22 re engined ...tank has pump etc in it reasdy to bolt straight into a ke rolla..

 

 

just as little red spirit said ...donkey

[Teddy]

Alright, lets play forum education 101.

 

i want to go to the beach.

 

"ohh, id love to to to the beach : )"

 

They mean the same thing.

 

But because the first one doesnt have blunt in your face emotion to it, does that automatically mean i am being sarcastic or dry?

 

No.

 

If i wanted it to sound like that, it would be

 

yes... i want to go to the beach. .

 

or

 

Yeah... Mmm beach

 

or

 

f@$k the beach.

 

Lets take this into context.

 

If beerhead wants to share his idea he will. - Ok, that says to me - If beerhead wants to share his idea he will - i can't see any knives or throat grenades yet, lets try the next line.

 

Coronas arent hard to find, try looking before telling me its hard. - Its factual, to the point & accurate. Lets remember that your doing a fuel system here, and without my personal view of i think the industry of auto mechanical and electrical should be registered like that of plumbing or building - your previous line of "my build is on a tight timeframe" - Ok, thats understandable - but safety comes first hey. I have no need to re-write this thread as to what is or is not safe - But when you also say "i'm just looking at getting it going first, then overcoming any obstacles as they arise" - That to me spells - Well, ill just make something temporary permanent to work for now, and if it pisses out fuel, ill deal with it when it happens"

 

At the end of the day, i don't want to jump on a forum band wagon and appear to be getting angry, when I'm not at all, (if i was angry, id have caps on, red text and bold. & you would know about it ) - its just when i know my friends, brothers, sister etc are getting into cars of unknown-ness, and there are people ALL around doing these half cast jobs - you don't want to be on the other end of me, when ive found out my lil brother has been admitted to hospital thanks to 3rd degree burns because fuel has started pissing over the hot exhaust & the cars set alight. I will re-make it clear - i am not angry as i am typing this... just understand where I'm coming from.

 

You really wont want to pull the tank out again once its running, and its seriously dangerous to get fuel surge. - I don't think i need to decompile that line;

 

Do it once, do it properly. - If thats the only thing anyone gets from any online forum or tech assistance - its that. Do it once, do it properly.

 

If personal assumptions are leading you to think that people are getting angry at you.. just take a step back and think twice. No one is here just to blatantly get angry... !

 

Where is my unicycle, i need to catch another mango flavored elephant. :(
