<VV> But Seriously Folks, Here's a Post About Fuel Pumps

[N. Joseph Potts]

Dave, do you care to share with us where/how you get KITS? Much of the
present plague affecting mecahnical fuel pumps arises from the "don't
rebuild them - new ones are too cheap" mentality, so I know of no one who
sells KITS for rebuilding mechanical fuel pumps. We've learned over the
years that there's a REASON why the new ones are cheap, and this is one case
where original, obviously, is FAR superior to replacements. Fortunately, I
haven't thrown away my old pumps. I've got half a dozen or more - good, bad,
and all ugly.

Steven,
I can almost guarantee that the pump surfaces are warped.  I started
about a year ago rebuilding my fuel pumps (plus several for others in
our club) just because I like to run original stuff.  I have done 6 & no
problems so far.  Interestingly, in EVERY case the diaphragms were FINE,
but the surfaces were warped.  As instructed by the folks I get the kits
from, I file the surfaces flat using a large file.  The worst one to
date was the "newest" one.  It was brand new, but the original vendor
box had been lost, so I don't know where it came from.  It was my only
spare at the time & I had been carrying it since I bought my car (6
years ago).  It lasted 6 months before it started leaking out the side.
When I took it apart to put in a new kit, everything looked perfect,
until I checked the flatness by filing a little, and wa-la, very warped.
I documented the same problem on 5 others that I did.  Although I don't
know where these pumps came from, or their age, it was obvious to me
that none of them had been filed, or cut flat.  They were just as they
came out of the casting.  Right now, my personal feeling is that I will
only run a pump on MY cars that I have rebuilt & checked or filed for
flatness.
