Fuel Pumps And Surge Tanks

[LINDSAY]

do not put high pressure through the carby lines!

 

either get proper fuel lines made up, or use high pressure efi rubber lines.

id go withthe proper metal ones

all this is covered on the internet in a few different write ups by the way

 

so even the metal fuel lines have to be replace for high pressure ones , i would have thought they'de good for at least 100 psi , cause i have just finished setting up the fuel system in my boot and i thought only the rubber lines needed to be replaced by high pressure ones .

where do ya get high pressure metal fuel lines from anyway ? or would braided line be allright to run under the car ?

heres a pic of mine Too quick

no no, the metal ones would be fine I'm quite sure.

i was saying go to either:

high pressure lines

or

metal lines

steel braided would be good, but exxy

Didnt think about the engine bay, Do the pumps need to be close to the surge tank to work effectively ?

[love ke70]

which pump do you speak ok?

i see no reason why the lifter couldnt pump fuel thru to the engine bay.

hay thats not a bad idear! I'm goning to look into this tomoro, becuse atm my fuel lines are kinked and need to redo my setup any way....

 

ill get back to yous.

[love ke70]

[Jason]

has any one got any pics if any ones done it before? Ive got a pretty good idear were to mount it.

With a tank being in the engine bay the lift pump will get fuel there BUT....

 

It will take a while to initally prime. When you key flicks the ignition ont eh car the high pressure pump starts and lift pump. So the added delay in fuel getting to the main pump could fry it faster. I would have the lift pump close to the main pump but lifter has to be in main tank so....

 

Unless you can fit a 555 time circuit so the lift pump comes on the say 5 seconds later the main pump comes on thus fuel should be at the main pump and reduce wear.

ummm there will still be fuel in the surge tank....

[camerondownunder88]

But ont he high pressure pump if it picks fuel up from the ottom wont the fuel run pass the pump anyway just get through it and crap? I

But if I think about it to even if fuel gets seeps throught eh vanes in the pump into the fuel rail the rail has the pressure reg on one end so it will hold the fuel there so...but I woudl still like a timer to make the car more spiffy adn just to have it..lol

 

As a 555timer circuit piss easy to do for any application..

if it seeps through the pump its only going to the fuel rail..... theres really no need for a timer circut as easy as they are.

[love ke70]

i want you all to put timers in, so that there are more wires and more things to go wrong :)

Can the lift pump be mounted in the surge tank instead of the fuel tank ?

 

EDIT: i think i will just mount the surge tank in the boot in the spare tire well for now.
