Fuel pressure regulator
This is an odd situation. The GT has mysteriously just quit running a couple of times, even at highway speed. Today while doing some fine tuning in the shop it did it again. The solution is to remove a fuel line, on either side of the regulator, relieve the pressure, and reconnect the hose. Then it is fine until the next time.
What is odd is that before we shut it down the pressure dropped from just below 3 to 1 pound. After popping off a hose and restarting the engine it stayed at 1 pound of pressure. It took two or three turns of the adjusting nut to get the pressure back up to 2.5 pounds.
My gut tells me that the problem is with the regulator. But not sure why.
When this happens the Holly pumps change sound, telling me they are not pumping. But I believe it is do to the regulator blocking the flow rather than a pump problem.
There is no return line. That would be a challenge with two pumps, two tanks, etc.
Wondering if any one has had a similar experience?
