HELP - fuel pump piston snapped
« on: July 15, 2017, 10:17:38 am »
I was just replacing the cam follower, and on pulling the pump out it got caught in the banjo pipe and twisted.

Basically the end of the piston has snapped off from the end of the spring.
Dont know if it was like it before as ive only had the car a week

what do i do? safe to put back together?

Appreciate the help

Can you buy the piston/ spring from anywhere?

Isn't this the part that you upgrade for better fuel flow? So there must be loads lying around in peoples garage's

Don't fit a second hand piston into a pump. Buy a whole second hand pump

Probably because another piston will have different wear to the part that it fits into on yours? - and therefore won't work properly.

Sounds like pretty good advice to me - a lot of very knowledgeable people on here

Buy a good used pump as already said.... Fitting a second hand piston is as bad as people buying a second hand rod/piston on eBay and just throwing it in to an engine. You're looking at £50-60 for a decent pump

I bought a good second hand pump.
It was the newer version without banjo fixing and the pressure release valve.
The top sensor was cracked and been repaired, was told it still works but looks nasty.
No problem I'll just swap the top sensor over from my old pump along with the banjo fitting, but I can't get the top sensor to sit at 11 o'clock like it should...ends up at 1 o'clock every time, anyone know why?
Dies the sensor need to sit at that angle?
