Any paticular reason a generic fuel pump wont work?

[E30godz]

I'm not sure if there is some crazy backassward engineering that would keep me from intsalling a generic (ie walboro) high pressure/high flow fuel pump? 1990 325i.

[e30evolution]

not that i can think of...... the question you should be asking is...

can i make a generic fuel pump work.

if you are using a stand alone fuel system there would be no problem.
even if you werent as long as the pump was turning on and making fuel pressure there would be no problem

if you can wire it, you can use it

[E30godz]

gotcha


theres only a fuel intake, fuel exit, power, and ground right?

[E30godz]

does this car have just an in tank pump?

E30Godz, I just made a thread about the Walbro fuel pump, I already purchased one, the 255LPH flow rate high pressure.

Check here for more info, BimmerJim also gave us his link with many pics of that pump installed/adapted in his fuel tank.

He is using the 300LPH pump, he told me is made for run lower pressure than the 255LPH, while the 255LPH can handle FMUs and that kind of stuff.






By putting this pump, you will delete the main/outside fuel pump and the little/secondary pump inside the fuel tank, will only run one super high pressure pump.

im fairly certain that my car only has one fuel pump, the in tank one. What part number is the walboro pump that you are buying Diego?

[E30godz]

and TCD needs to post on E30tech in the "most powerful M20 bottem end in the US" deal.

he put out like 270 HP non-intercooled

edit: Diego, what size injectors are you running again, and what FMU?

About the code of the Walbro fuel pump is writed in e30tech,, in that article, I don't have it right now in my head. Just searcj for a Walbro of 255LPH of flow.

I'm runing Jeep Cherokee (SIEMENS) 21LB/H injectors with standar Vortech FMU 10:1

So far I know, the e30 has two fuel pumps, also the e30 3, a pre pump wich is inside the tank and pumps to the main pump that is out side, next to the fuel filter, at least that's how my OEM system is.

[E30godz]

Yours is an 87, i think they may have switched to a single pump.

Dunno, but I have two pumps on my bimmer

[E30godz]

Diego, in the pics BimmerJim has on his fuel pump, what do you think he is ripping off with those pliars? Looks like some sort of bracket.

i ordered a Walboro fuel pump with part number GSS342. 130 bucks shipped.

Check just infront of your Driver's side rear wheel. You should be able to see the cylindrical in-line fuel pump if you have one.

Its easy to convert in-tank to external. I've done it on a jeep cherokee

[E30godz]

i checked the bentley, only have the in tank
