Fuel Pump Rebuild
Posted: Sat May 19, 2012 10:23 am
I decided to rebuild my fuel pump because every time I left the pinz for a few days without use it would take ages to start. It wasn't always like that and it was getting worse.
I'm not a mechanic. This was very much a DIY job.
These are the bits I used for the rebuild:
A fuel pump repair kit, part number 712.1.08.560.0
A 13mm open ended spanner
A medium flat head screwdriver
A small flat head screwdriver
Two hose clamps
Some grease
The repair kit contained these parts: The idea was to remove the fuel pump, change the old parts with the new parts and then put it back again. Easy right? Well, yes it was actually.
To gain access to the fuel pump I removed the engine cover and then took off the air filter. Here it is: See the wet patch under the fuel pump. Something is definitely wrong!
Before removing the hoses from the pump I clamped them about 2 or 3 inches from the end to minimize fuel spillage. The manual says to pull the hoses off. I found that I had to twist them to get them off. Then they came off quite easily.
I tucked the hoses out the way and used the 13mm spanner to remove the two nuts at the base of the fuel pump. They are not the most accessible nuts, but fortunately I found that after loosening them about a quarter turn with the spanner they came off the rest of the way by hand.
I removed the two washers and the pump lifted off easily. I also removed the push rod that was sticking up beneath it and the black plastic bit that the pump sat on. I looked at the base of the fuel pump and saw the lever which gets moved by the push rod. I pressed it with my thumb and petrol squirted out like from a water pistol. Something to look out for!
This is the removed fuel pump, nuts, washers and push rod. There is a gasket still on the push rod: I'm glad I took this picture because I had to refer to it later when I reassembled the pump.
