Fuel pumps

[Sherlock]

Ok so I know this has been covered and I'm sure with some more research I'd find a vague answer but...I'm lazy and like good answers.
I also figure there are a lot of members such as my self who are after a simple answer (Davey I'm looking at you ).

SO, I'm going 4AGE in my AE71 in a few months, yay for me. Fuel pumps are my issue, I know very little about them.

By popular demand, a bit of light reading and some advice from a few members I've been told to get this (or close to):
- 1.5 litre Surge
- Bosch O44 (VL Turbo)
- 4-5 PSI Lift Pump

Now all in all new that's going to cost me about 550...I don't mind spending that as it seems it is a proven method of fuel delivery.

BUT, I was wondering if there are any alternatives? The questions...

What other alternatives are their to delivering fuel? (In-Tank pumps?)
Can an in-tank pump be used in a KE70/AE71 tank?
If I do run an in-tank, is that all I will need, just the pump?
What in-tank pump should I run, if it suits?

Feel free to drop some links of info, give your opinions, answer my Q's. Please No stupid answers, or use-less posts...
Thanks in advance guys

Same setup as mine for the 4agte.. Works well but i would go for under car surge tank

Why do you say that?

As you need to cover them up to race.. they stink when u stop the car and then return.. They sound quite annoying. and fuel pumps are easy

VT commodore in tank pump with swirl pot (surge tank). Supports 400hp. I had to machine a new ring for the tank and weld it on, plus another one that sandwiches the top flange of the pump setup against the ring on the tank.
Since I did the fabrication ($25 for some heavy steel pipe), pump bought from self-wreck ($36) total cost with a new seal ring is around $65

I'd used a VL Commodore in-tank pump because this can be attached with just a very short peice of fuel hose and two hose clamps. there a link somewhere on how to do it..... very easy though

heres the link:


and i just ran a new VL Turbo external pump, but I'm not running a surge tank at the moment.

Hope this helps!

[dustyae86]

that high pressure pump is overkill, sure everyone is running them, but it is a huge pump thats not necessary, otherwise it sounds ok, I'm doing soemthing different soon, so i can hopefully jsut run one pump but can't be bothered explaining

[Tyrie]

044 would be overkill, VL pump would be ideal. VL pump is NOT 044. I have never seen a VL with an in-tank pump, also VL turbo and normal VL pumps have the same part number

Tyrie, Vl's have small ift pump to feed the external pump they run.

70/71 tanks have too small an opening at the top of the tank to get a good pump in there. AE86 tanks have a bigger opening so an intank pump from other cars can be adapted to fit. i use commodore in tank pumps or whatever i have around really, doesn't take much to keep fuel up to a N/A GE.

never had issues with surge above 1/8 of a tank. really shouldn't run an EFI setup car that low anyway apparantly due to the pump picking up shit in the bottom of the tank, never had an issue myself, probablyjust one of those internet urban legends.

[n00bvak]

as always, gilly is correct. I have just bought both to feed my ke70 gte.

vl lift pump -> vn commo fuel pick up -> surge -> bosh 040(vl turbo) -> rail -> malpassi rising rate fuel reg -> surge.

Read the above link that sprinter86 posted, that got me started.

But if it is not boosted, there is no need for surge, seen first hand that it is not required on NA 4ag's
