Whilst was adjusting the fuel pressure (with a pressure gauge on a
T-fitting described in Wes I's SPICA booklet) in the GTV to be between 8-10
psi, I noticed that gas was running down the right side of the pump. The
engine was off and the fuel pump was the only electrical item that was ON.
Strangely, I couldn't smell the gas but saw where it was dripping down to
the ground off of the pump.
I thought that the threaded barrels that hold the hard lines to the pump
were loose, so I re-torqued each one (15 ft lb) but it still leaked. The
gas was running out from under the small bracket that holds the nuts in
place which in turn hold the treaded output connections to the pump. I
think that only the threaded connection closest to the radiator is the one
that is leaking. I've never seen this before, the pump has always run
without any gas leaks.
I've never messed with these threaded output connections but I gather that
there must be a seal of some sort underneath each one. Do you think that
retorquing the threaded output would fix it ? Is this something that I
can.should do ? Or does this indicate that there is something wrong deeper
inside the pump? I've already sent a note to Wes about this today.
Obviously, I"m not going to continue trying to adjust the fuel pressure
until this is resolved since the leak affects the reading.
Thanks,
Bruce
I've got another SPICA pump and I'm going to have a look at the threaded
output connector and see what is below it.
