Oh, I did want to check if anyone had any ideas on why they fuel pressure is
so high? This just doesn't seem correct and it seems odd that he has to have
the pressure meter in line to control this. Has anyone ever heard of this
happening with a brand new fuel pump that is correct for the year (has the
lever)?

Subject: [TR] SU Fuel Problem
A friend of mine is having problems with his SUs that we just can't figure
out. Here is what he is experiencing:
My 1970 TR6 is seeping fuel out of the rear SU float bowl overflow tube.
The SUs are a new Moss Motors conversion set. I called Moss about the
problem, but they were no help. I installed a heat shield, but that didn't
change anything. I installed a new Moss fuel pump, but found that it was
putting out 7 lbs. of pressure. I next installed a fuel pressure regulator
and dialed it down to 2 1/2 lbs. I thought my problem was solved. Today I
drove the car 140 miles in 86 degree weather. While driving I thought I
could smell fuel and when I returned home, I popped the bonnet and could see
fuel dripping from the overflow tube and it continued to do so for a short
time after the engine was shut down. Anyone have any ideas as to what is
causing the problem and how it can be solved? I am stumped.
Thanks.
