Gtst Fuel Pump In Gtr?

[chch34]

I have sold my standard GTR fuel pump from my R32 GTR and bought a factory R32 GTSt fuel pump, and an aeromotive A1000 external pump ( this one ). I need to shift my car to the other side of town, but i cant get a surge tank for 2-3 weeks. Will my car run on just the GTSt fuel pump? Or will it run with low fuel pressure and cause my car to run lean? And an external fuel pump must have a surge tank/swirl pot, correct?

Thanks guys!!

I do believe it will run fine, provided you arent maxing out the gts-t pump. If you could keep it off boost ~4-5% injector duty cycle, then i dont think you would have any problems

Stupid sounding question ->

So does an external fuel pump need a surge tank?

[kenetic]

Usually you have your standard in tank fuel pump feeding fuel into your surge tang and then have your external fuel pump pumping fuel from your surge tank to fuel trail (existing fuel lines)

Unless you plan to do a lot of circuit work / drag racing I see no need for a surge tank.

You can even get away without having one as long as you keep your fuel tank full.

I doubt you'll have any fuelling problems - it anything it will probably run rich - I know of guys that run a standard r31 non turbo pump in tank and use a bosch external in high hosepower applications. Your external will give you plenty of fuel pressure.

get a fuel cell lol.... where u getting u tank from man??

These are the specs of your pump below, now why are you buying one of these at $290 US when you can buy a bosh or walbro pump that will give you close to the same sort of power I think the walbro in tank supports up to around 450kw (could be wrong on that figure) sorry to be so negative but it just seems like there is a lot of better options locally and for less money.

Specs:-

For carbureted powerplants making up to 1200 HP and fuel injected engines:

up to 700 HP - forced air induction

up to 1000 HP - naturally aspirated

up to 1200 HP - carbureted systems at the track, on the street, and in the water.

Yea ill probably just put it in line without a fuel cell for the mean time.

havent got a fuel cell yet matt, where should i get one from? maybe we should get someone to make up 2 for us (1 each!)

Yea if i were buying a fuel pump id buy a walbro or bosch, but i got this real cheap, so im going tyo use it.
