I have a 32' 89 Fleetwood Pace Arrow 454 Chevy carburated engine P-30 chassis
I had a leak in the Fuel Pressure Regulator, due to broken diaphragm. I was able to find another diaphragm and replace it. I drove the RV over 1,000 miles. It only stopped on a very steep incline and could not get it started. Once on level ground I drove it another couple hundred miles. Then it was not getting enough gas and stopped again. I bought a new fuel pressure regulator and am going to replace it. After adjusting the regulator I drove it with the new diaphragm but had a hard time adjusting it to the right pressure. It does not get enough gas and the exhaust sputters and backfires. Does anyone have any information about how to adjust these regulators. Or is there another pump in the fuel tank that could be at fault. I appreciate any replies
On a 1988 Dolphin motor home, I replaced the failed engine driven fuel fump with an electric pump. Now, the fuel pressure is too high. Where is the fuel pressure regulator on that type of vehicle, with carburetor.
