Re: fuel pressure not stable
Agree, replace gauge and/or spray the gauge with a can of keyboard duster, its CO2.
You could also remove gas cap when the gauge reads close to zero and observe if pressure comes back up.
And you should be able to suck on cap in testing vent, and it is a one-way valve - pressure in, no pressure out.
As Kevin suggests, if engine runs as good when warm as it does cold, throw away the gauge - problem solved.
A short test of mechanical pump is see if it will fill a qt bottle in about 15-20 seconds, +/- 10, maybe 15, at idle speed.
Mech pumps only provide a volume of fuel, not pressure.
