Decided to pull apart and rebuild my tandem pump. Had a very small oil leak from the rear cover seal.

Post-sanding. 1st with 100 grit, then 220. Done on flat surface.

What size torx did you use to get the screws out of the fuel pump side? T25 is too big, T20 is a bit loose and I stripped two of the screw heads. I cannot find any torx bits between those two sizes. I have the same repair kit you used but the replacement screws for the fuel pump side have heads that are too thick (too tall); they are not the rounded heads shown in your kit.

I think I'll just replace the seal and not disassemble it any further.
