I went to wings and wheels today and on the way home on the motorway the fuel pump made a noise. In the past when it did this I swapped tanks and ran on the other for a while the swapped back - no further problems. Always thought there was muck in the pipes or whatever.
Oh yes I run efi tanks to polack to lp pump to swirl return to tank then swirl, up pimp fuel rail to swirl Total of two pumps noisy pump is the. Hp one.
Anyway today I did just this and the pump quietened down as normal. I got home and terrible fuel smell and I found the left tank spilling out the fuel cap. At that stage I was drawing from the left tank so no way should it be full after a few miles drive!
After a half hour by which time the spilt fuel had evaporated and the car cooled down. I selected the right tank and it was showing one quarter. Ten minutes earlier it had readvthree quarters. So immediate thought is that on swapping tank to tank the Pollack valve has broken allowing fuel to draw from the right and return to the left thus causing the left to "overfill"
Has anyone had a pollack valve let go like this?
