RE: Fuel pump problems

[Tom Duross <tduross1@xxxxxxxxxxx>]

With traditional "plumbing" when we install a pressure regulating valve, we
always install a safety relief valve after it on the low side and either
pipe it to waste or back to high side.  Maybe a return line back to the tank
with a regulator on it might help also.  You should try and get adjustable
regulators, use fittings that can withstand the pressure and set them for
whatever pressure (or range) your carb requires.  The safety valve is set to
open if the regulator fails.  Sorry for not specifically addressing your
problem but maybe this is of some help.

Subject: Fuel pump problems


Hi,

My engine has been running very poorly and the exhaust smells really
rich so this weekend I put the fuel pressure gauge to it and it pegs the
gauge at 6 psi (I don't know the actual reading since the gauge will
only read to 6 psi.).

Went to the local AutoZone store and got a fuel pressure regulator.
After installing the regulator the engine is running better than it ever
has.  However, after about a half hour of driving around the regulator
is now leaking and spraying fuel all over the engine.  It is amazing
that it didn't catch fire.  I would like to eliminate the pressure
regulator.

My question is; is there some type of fuel pump failure that would cause
the fuel pump to put out too high of a pressure?  In other words, will
replacing the fuel pump solve the problem?  Also, the engine is a Poly
with a Chris Nelson cam and Eddelbrock 600 CFM Performer carburetor
(1406).  Does the poly take a different fuel pump than an LA engine?
What is the correct pressure for a Performer carb?

Thanks in advance,
Ken
