Hey guys,
Still trying to locate my problem with the fuel starvation on acceleration. Both fuel filters have been replaced, so now I am looking for the vent on the gas tank to see if it is plugged up or something. Does anyone know where the vent is on an EA-81 hatch and how to check it? Any common problems here? Thanks!

Bill

test your pressure from your fuel pump. also, take a look at your float. It may be adjusted incorrectly or have moved a little over time.

I will check that out too. The problem usually happens when the car has less than a half tank in it and it will do it intermittently when accelerating under load (going up a hill). Acts just like it is running out of gas or something. It recently has gotten a bit worse in that it will now start to do it when the car has 3/4 tank in it. I am completely baffled. Do fuel pumps have to work harder to draw out fuel when there is less fuel in the tank?

Still have the problem. Even though I recently replaced the vapor separator, i pulled the vapor line off the top of the separator to look inside it to see if it looked plugged up. When I removed the vapor line, there was a long hiss like there was a vacuum built up. I also heard some gurgling sounds coming from the gas tank when it was hissing. Is this normal. And should the separator have lots of liquid in it? Thanks.

Bill
