Surge Tank Opinions

[Biggo]

Well i have a suge tank...

 

Now its a custom jobbie which makes it hard for me to determine its orignial use. I.E do i fit the return line from the rail to it and let it have a drain to the tank or do i need to have a breather line like the tank thereby eliminating the above idea?

 

heres a (rough) drawing of my tank:

 

return line -

return to tank -

inlet -

 

 

 

 

outlet -

 

excuse the crappyness :dance:

 

i already have all the line/filters/fittings and just need to know what to do with them :abuse:

JC807 - what are you useing for a lifter pump? name + part number would be useful. If i could scab your setup for a day id be in heaven :dance: but sadly i aint and it wont happen. Anyway, are you useing a relay for the 070?

[Jono]

lift pump is a high flow/ low pressure "facet" pump. will dig up the part number for you. Yes will be using a relay for both pumps.

Hey JC807 why wouldnt your order be

 

Return

Fuel Rail Return

Low pressure in

 

Makes more sense to me that way???

[oh what a nissan feeling!]

The return line can be returned to either your fuel tank or surge tank. The problem with returning to your surge tank is that the same fuel can pass through your fuel rail several times, because it is only getting mixed with a small amount of extra fuel from your surge tank, the fuel your car is receiving can actually get quite warm, this will effect overall power cos fuel burns better cold. The advantage of this however is that your lift pump can be small, almost any low pressure pump will do.

 

The other option of running back to your fuel tank eliminates this problem, but also means you need a much better lift pump.Like a holley red for example(depending on pressure pump size). Remember also that your fuel return line should be as large as your pressure line. :dance:

sweet, thanks for your help guys.

 

So far ive done a lil trickery and changedsome lines around so it flows better. will fill it out later when its all hooked up and ready to rock! :dance:

here is the one i did

 

 

That what i need,where did you get the little tank from and what are the pump part numbers.

 

PLEASE!!!!!!!!!!

[Biggo]

...ebay :dance: thats where mine came from

 

so from all reports i should got

 

rail return -

tank inlet -

overflow -

 

 

 

to fuel rail -

 

correct?

[oh what a nissan feeling!]

That order will do! :y: If your fuel tank is below your surge tank then the overflow must be on top.

Also, if your fuel system is 'as above', you must be careful to buy a lift pump that will pull as well as push.Aftermarket Fuel pumps are usually designed to push only, so lift pump should be picking up from the bottom of tank, with pump mounted below your tank. Push and pull type pumps are available, but are harder to find.

 

If the above setup does not have a push and pull type pump, then it is simply relying on a syphon effect, which i guess would work........ but do you really want to? :hmm:

Yeah thanks for that but what are they.

[Biggo]

Mine came from a private seller hence the thread. Jason bought a poopy bay store one, so ask him about it.

 

Mines all hooked up now, will do a (very) informative write up if anyone wants/needs it?

[Jason]

lolz :hmm:

 

i used a VL lift and main pump, the lift pump will go inside the ke70 tank

 

u just need a diagram
