Bosch 040.. Warning

rmagictastic · August 17, 2006, 01:43:36 PM

I seem to be like the angel of death these days, issuing warning and problems ive had...

so here we go again.

Ive got a Bosch 040 fuel pump in my tank. I started to get a funny problem that when i boot it in 2nd or 3rd, it started to get a massive judder/backfire type thing happening.

After MUCH investigation, it turns out that it was fuel starvation, my fuel gauge was showing just over 1/4 tank, so i missed this at first.

SO, no matter what people tell you, if you have an 040 please ensure that you keep enough fuel in your tank.

BTW, i still think that the 040 is a great pump, and this shouldnt put you off using them.

cheers

Are there any alternatives to this? Is there any reason you should have to put up with a pump that needs 1/4 tank of petrol to function? Just wondering.

Id heard that the 044 needed to have 1/4 tank in it....As I understand it, the walbro doesnt...

does the FD tank not have a swirl pot in it as standard ?

Most modern injection cars have a swirl pot built into the fuel tank to stop fuel surging like your suggesting.

an 044 is an external pump not internal

i know you have an 040 i was refering to one2watchs post

a swirl pot is really a good idea if one is not fitted as standard

a tank in the engine bay can be fitted, or some people modify the fuel tanks themselves

Do you think you will get the same problem with an 044 ??

rmagictastic · August 17, 2006, 01:58:50 PM

sorry geezer, was confussed, yes a swirl pot would be a solution.

Oh yes and thanks to Slippers, for his technical advice on the matter.

I was told by Pip that the Walbro is fine.....I spose the other option moght be a supra pump?

Ref to above post, the 044 needs to have atleast 1/4 tank fuel in it.

CraigN · August 17, 2006, 02:01:23 PM

with a 044 i would do it differently

keep the intank pump and place the 044 in line jsut to increase the pressure
if you were to use a swirl pot like this

you would use the low pressure intank pump to feed it and the high pressure pump on the outlet then to the fuel rail/s

any decent pump is going to require a decent ammount of fuel in the tank if there is no swirl pot built into it, corner hard and any pump will be starved be it internal or external.
