A Bosch 040 Failure?

[nisskid]

so for a while, ive had this wierd grinding that has come on and off here with a strong humming. lately it has got worse and worse, so eventually i popped the boot and listened to it on idle and as i thought it was coming from the pick up where the fuel pump is.

now i had just recently replaced a f**ked stock one with a bosch 040, even had it installed by boostworx whos a very reputable shop in SA, so its left me puzzled as i have bever heard of one of these failing before. now ive gotta go have a look for the warranty papers

[Gts-t]

Mate of mine had a few let go in his 180 recently. He had heaps of crap in his tank tho lol, might be worth a look.

[T04GTR]

no. there just shit. lol ive turned blu in the face telling people they just dont work.....

cold ok. hot gay.

[dontfeelcold]

Is that for all bosch fuel pumps?

Hey Stew,

Are you able to describe your setup? Is the 040 where the stocky was? Same pick up height?, sock filter?

I'm thinking of late, this is how many die, and how they are getting such a bad rap

Im not sure what hot gays have to do with it, but as long as industry continues to use em, so well I

[shnaped_second]

Ive put a few of these in my cars and have never had a problem, but have heard of some ppl having nothing but trouble, maybe its got to do with all the copies getting around now...

[Gts-t]

For what its worth my mate had a HEAPS of crap in his fuel tank.

On another note, im fitting one of these pumps soon and moving my 044 from intank to after a surge tank. So well see how that goes, ill report back if the pump ever fails.

to be honest i do not know as boostworx put it in. i can pull it out and have a look if need be. boostworx are a reputable workshop, and it seems to pick up as much as the stock one, if not a bit more.

[WogsRus]

i don't know why you said suprised, i have ahd 6 let go over the past 4 years.

[nisskid]

it was kind of a piss take after how many people always reccomended them saying theyd never had one fail etc.

[T04GTR]

just the 040 in a standard fuel tank.

lol.

yeah i replace them for the fun of it do i???? ever put a fuel pressure guage on one from cold to hot and see the pressure drop down to 10 pound when the fuel heats up? if not your driving a time bomb.

but its ok. you simply turn it off and re-start. and wait for it to start cavitating again.

[T04GTR]

the pumps themselves dont fail. the way they are mounted is important. if they recieve any sort of air bubble then they cavitate and loose pressure. they still work but they dont operate in fuel over about 30degrees

besides they only put out 10% more than a gtr pump.

[R31Nismoid]

Ive never had a problem with Bosch pumps

I could name you dozens of cars that dont either.

That said, if one died. Its gonna happen. Could be due to heaps of things

[Ronin 09]

how about 044s?

To start with, if you didn't have the tank removed and cleaned...and can show proof, then no warranty will be had. Also...who said the pump has failed. Just because it makes a bit of a noise. I have used a fair few of these before without failure on a single one. Doesn't mean it can't happen but it's highly unlikely. The noises can quite possibly be coming from the standard mounting frame which the pump will vibrate against if it has no padding between itself and the pump. Also if they are mounted too low they can vibrate against the bottom of the tank.

Noise doesn't mean stuffed.

[T04GTR]

yeah. like they dont fail there output just drops off as the fuel heats up. happent to me and 3 of our customers. they pumps them selve ae fine. they just went operating properly.

kinda hard to explain with out a 10 min long video showing exacly what gos on.

th o44 is a gem. no dramas regardless of mounting style

(lol @ spelling,dialing wand needed)

Shaun measures the length and sets them up correctly. So yes.. Exactly the same height as stock.

Bosch pumps do get groany when the fuel heats up. When mine wasn't receiving full volts it was so bad the floor pan would vibrate and could be heard/felt over the radio.

yeh, i read the warranty, bit annoying.

i used a question mark in the title because i was asking a question, i wasnt stating it had failed. it still seems to be working, although i have noticed some stuttering, but in saying that i have fitted an RB25 turbo recently.

its been a deteriorating issue, it has been getting worse over time, now considering i have driven in 43' heat and not had this problem, but now driving in 20' heat and having it worse than ever doesnt seem to make sense. the noise happens here and there, not every time i drive it. happens when its cold (just reached or a bit below operating temp), hot, doesnt matter.

the humming is one thing, but the loud scraping noise is a bit of a worry.

ill take it to shaun and see what he thinks, if its just the noise, im not fussed, but when i hear something like that, i want to make sure im not going to have to be picking up pieces of my engine any time soon.

went to turn on my car today, turned the ignition on, but didnt hear any fuel pump buzz like usual. so went to crank it over, started terrible like usual, did it again and gave it a bit of throttle and it made it. turned it off, tried it again, no fuel pump buzz, cranked it over again, started just as bad again (which is unusual), kept repeating this and never heard the fuel pump buzz, not sure whats happening. the noise wasnt very prominant, but like i said, it happens here and there.
