What causes excessive pressure in the fuel tank?
What causes excessive pressure in the fuel tank?
Nothing like I have heard on any vehicle, at any time. The fuel pump, gas cap, and fuel evaporator cylinder are all new. The gas cap, fuel pump, and gas evaporator cylinder have all been replaced and the problem still exists. Do you have any suggestions?
What does OE do to the fuel tank?
OE Pressure relief prevents fuel vapors from exiting the fuel system under normal operating conditions. This allows an escape path for pressure in the event of an impact situation where the fuel tank has collapsed.
What should the pressure be on a gas tank?
They said no matter if the tank is full, in theory I should be able to suck or blow air through the vapor line connected to the tank with only about 5-10psi. They said the screen filter also acts like a pressure regulator and the valve on the gas cap should also be letting air in and out as pressure or vacuum builds.
What causes excessive pressure to build up in my 1996 Ram 1500?
What causes excessive pressure to build up in the fuel tank of my 1996 Ram 1500? When I remove the fuel cap to refuel, there is an excessive amount of air escaping from the tank. I know that some air would be normal, but there is a lot.

Is it normal for gas tank pressure to go up?
The gas cap is desinged to vent at a given pressure. If the tank is almost empty it will have more volume to vent even if it has no more pressure, that is normal. While it is hard to say, I would not consider your expereience to be an indication of a problem. If you really want to try something try a new fuel cap.

What causes a gas tank to bulge at the bottom?
If the fuel pickup and level float are anchored to the top of the tank, plus pressure buildup causes the tank to bulge at the top and bottom…. the pickup and float could be lifted from the fuel, changing the gauge and starving the engine.
