Fuel cut out on long corners

[Jean]

Two different solutions.

Alright after a track day this weekend I'm sick of this, one longish highspeed corner (60-70) and a gas tank between 1/4 and 1/2 a tank causes my engine to cut out from all the gas going to one side, not being picked up by the pump, does anybody have a remedy for this problem on the track?

you posted in the original article ^ about this. So you want to use an accumulator? it appears Jleivies 'solution' keeps everything in tank using later style tank ? or am I missing something here- 2 different solutions w/ diff tank styles/systems interesting discussion /education . Thanks all

Which E30s came with a pre and main pump, also would just adding a more powerful pump help solve the issue?

Pre 88 or 87 cars iirc.

The Audi accumulator trick only works on e30s with pre and main pumps systems.

A surge tank is usually located in the trunk and also needs a feed pump and a pressure pump.

Check your hoses around the fuel filter.

That's a pretty old trick from 20 years ago. Basically one small cylinder with one inlet (from the fuel rail) and two outlets (one feeding the main pump, and one for excess fuel back to the tank). It doesn't work as well as a full size surgetank, but surely a good safety measure for most of us because the main pump is fed by the tank AND the fuel return.

Is this is for 1 pump system ? or what am I missing here !surge tank is generally locate where ?
thanks

No problem Lee

Ill have to dig it out but im pretty sure its an Audi part

He, he. For the benefit of the community. There will soon be a scavenge hunt at Audi scrapyards. Another $5 fix.

Hey Joel, would mind posting a picture of the accumulator. I am curious to see to what car it belongs. Should be from a 1982-1990 Audi but not sure.

ive got a fuel accumulator that i never used. PM me

Also, i had this problem on a 318is. turned out that the filter screen fell off the pump, allowing it to move aorund in the tank. may want to check that.

Awesome info guys, I didn't know there were so many solutions.

Lol....got a pn? I can see if I can get it cheaper locally :)

BTW IE's accumulator is an... Audi off-the-shelf part.
