Walbro 255 fuel pump install
pump carrier out
Uncliped all the electrical connectors so two halfs can come apart
Filter was a little dirty, uncliped the plastic bracket that secures the old pump in place
pushed down on the electrical connector on top of the old pump to slide it out,took a bit of force.
swap over the rubber seal at the top
Remove the locking spring washer that keeps the filter on the pump
sawed off the 3 tabs at the bottom of the pump
Then you can fit the cap back on (see picture to see which 3 tabs to saw off, you will maybe want to test fit before you attach the filter to the new pump)
Then swapped over the plastic and rubber o-rings from the old pressure regulator
Drilled a hole using a 10mm drill(had to also file it larger as I didnt have any larger drill bits not much filing tho)
so I could fit the 90* AAM fuel return pipe that will eventually connect to the return line. (instructions were not great to find which way the plastic washer and rubber o-ring went, may have got this wrong but it seems a tight enough seal.)
Connected the top 90* pipe down to the replaced pressure reg which has a fitting on it
This was a nightmare to get off used a 1.8mm drill bit to increase the swirl jet size
All back together, but had to problem solve, the two units would not compress. Noticed that one of the tabs on the pressure regulator cap was fouling against the swirl jet housing, just needed to pull the housing to the side to allow the units to compress properly.
