Well, a little searching found a V5 tool seal set for $23.99

I would still need a snap ring tool (i have) and the clutch tool
(which i think is on the autozone tool loan program).
Is it a crap shoot? You Bet. But i know the pump works
And a replacement pump is hundreds of dollars. I also have seen
many post about people buying replacement rebuilt pumps only to have
them leak too.
