i found out that it was going to cost me $41 for a rebuild kit for my fuel pump and $92 for a complete new pump with new fittings and clamps ,it isnt realy worth rebuilding for that price ,and the new pump has alot more tension when i push on the little level/arm ,so it could also be better for reving an engine harder as it may stay in contact with the cam lobe instead of skipping at high revs ,maybe ...
