i can hear my fuel pump whining anywhere after 80 mph, so i feel its time to replace it. since this is my commuter car, i feel this is something i want to be able to rely on. ive seen a couple brand new oem pumps on ebay that fit "most" e30s, but they ran for about $200. anyone tried this? claims to be able to supply enough fuel for high powered cars, but its good for a stock replacement (i know you cant believe everythin they say)

if someone could recommend a cheap fuel pump thatll fit our cars, thatd be great.

I think this is a variation of what we call here "the quick and dirty"
1) Get a pump like the ebay one or similar one from a salvaqe yard - Corvette is good and has a sock filter.
2) Cut the down tube on the stock pump.
3) Connect the new pump to the down tube with a piece of fuel line.
Adjust length to same depth as OEM pump. Still uses OEM wiring to pump.
Idea stolen from Euro-Nation.

I gave a 91 chevy cavalier wagon to the kid across the street. It had 225,000 miles on it when I gave it to him last Christmas and the fuel pump was making all kinds of noise when I got the car two years before that. It still runs fine.

Are you sure you're hearing the pump and not the fuel going through the dampers? That's what makes all the noise on my e30.

The last thing I'll say about a fuel pump is bosch makes a damn fine pump. The pump in there is how old and you are thinking about replacing it because it's noisey. If you replace it with an OEM pump do you think you will have to even think about it ever again as long as you own the car?

That kind of piece of mind is worth it.

you make a good point, but i figured since i have non-FI intent for this car in the future, i could knock out the fuel area right now since its due. and i know the sound is not normal, it has its on and off days. sometimes its quiet and normal, other times it howls louder than my exhaust.. if a 255lph fuel pump and an adjustable or 4.0bar fpr get put in, would standalone or aftermarket tuning be required? i know more fuel, more air and vice versa. i figured this might also go well with the maf conversion when bmwman works out the kinks.

well if you are going non FI then does that mean carbs? Twin Webers maybe? That means 7psi max if I'm not mistaken, with something like 4 psi nominal.

I don't have an answer for you, just I have a grage full of crap that I bought with the "plans" to use it including a brand new and complete ready to bolt on twin Weber set up for one of my e21's.

Whatever you decide, get what you need now, and buy quality or you may be buying it twice, whatever "it" is.

(helluva deals are not covered by nor meant to be covered by the preceeding statement except where quality is concerned)

FI is what the young-ins call Forced induction.

The contaminants, water, and dirt in the fuel are what destroys pumps. It's not uncommon to have a "fuel pump failure" and find the sock filter over the pickup completely clogged. Fuel lubricates and cools the pump. The fuel pump sock is to keep big pieces out of the pump. The main filter in front of the left rear wheel, is to keep small stuff out of the F.I. (and I mean Fuel Injection) system.

My 1991 318is had all the receipts for maintenance at the dealer. There was one for a fuel pump, filter, labor, and tow bill for $360. It had 110,000 miles. If that's normal, I'm cheap.

haha yall old folks juss gotta keep up wit tha times.. im only 19

anyway, my plans for this car are to make a high revving go kart or rally/auto-x car. since our 318s are so well balanced, i plan to have a well built suspension way before any more engine upgrades. it might lead up to a stroker in the future, as they are becoming more and more popular. but we'll see what happens.. until then, im thinkin MAF with itbs, some headwork, and full air/fuel.
