Hi there

I have an 89 mfi escort xr3i. i have a high pitched sqeal comign from my fuel lines in the engine bay. I have replaced the following with brand new items: Fuel accumulator, Fuel Filter and Fuel distributor, all to no avail. The noise is only apparent at idle and when the foot is taken off the throttle. When applying the gas no noise.

I have also had the problem where with sustained pushing, the car pinks and gets steadily worse the more you push on. Timing is fine, spark plugs are fine as well

Any ideas?

do you run a power boost valve? if you do its that, or your standard pressure reg.

have heard a similar noise and it was that

check you fuel pressure as this maybe the cause of pinking etc

Hope this helps

Fuel pump could also be getting tired.

on mfi's its not possible to mount a pbv...

if your car pinks (and if everthing else is ok) youll have to set up the fueling... most probably poor mixture...

good luck
