PS pump reseal

Well hell, why not start a war of words as don't totally agree Bernie...if 
you're pulling out the pump and have the whole seal kit, I'd replace all the 
seals.  If you're competent enough to do one seal, then I'd say your 
competent enough to do them all.  Yes statistically there's more chance for 
error, but if one seals failed, what's to say anothers not around the 

No extra cost, and my experience is the lion's share of the PIA on that job 
is pulling the pump.  It's a messy affair.  Also, having a good bench and 
vice is VERY helpful to secure the pump on removing and reinstalling the 
x-caps.  I'd also recommend one of those hammer/impact wrench jobbers.

IMO, you're asking for trouble if you fix what ain't broke!  Wash the pump
down with Gunk and find the leak.  Most probably just one of the cylinder
head O-rings.  Replace just the leaking one.  You can buy the O-ring for a
few cents, return the seal kit.
