Hi all,
I've just swapped my Lucas pump for a Bosch but when I got it running the idle was awful and it was making a hell of a noise / smoking a lot.
What I've done so far:
Checked timing - fine
Adjusted fuel pump position - no difference
Checked stop solenoid - clicks when ignition is on
Replaced all of the leak off pipes
After using the primer bulb a few times I noticed it didn't stay firm for very long so I loosened the unions and cranked the engine to see if fuel was getting through - only one pipe had anything coming out of it and it was mostly air! (How did it run like this??) I've checked all of the pipe work and replaced every clip but still no difference - the bulb goes soft within 30 seconds but seems to fill the filter housing / pump.
I've also re-seated the fuel filter / housing, tried a different primer bulb, loosened the return banjo (fuel comes out after a bit of air) After pumping the primer I sometimes hear air from somewhere close to the pump but I can't pinpoint where.
