My '85 builds up pressure especially when the fuel drops below a 1/4 of a tank, it's always done that so I take it as normal.
Sometimes when the gas cap goes bad it will cause pressure in the tank,also you need a little bit of pressure in the tank,or the car wont run correctly,like if you leave the gas cap off after filling up with gas.
That hissing sound is normal pressure build up from the fuel pump and nothing to worry about - pressure which is also NECESSARY for the vehicle to run at peak eficiency and why you should ROUTINELY turn your gas cap until you hear it click when putting it back on after fueling.
A fuel tank pressure sensor is a device used to measure the pressure in a fuel tank.
A Breather Cap within the guidelines of Manufacturers Specifications
It is normal for fuel tanks to develop positive and negative pressure as the car operates and the temperature changes.
Its Normal, Its Just Releasing Pressure.
Make enquiry's with the manufacturer of the compressor and get the max pressure rating. Then let the pressure in the tank build up to that level. If it does not open get a new valve
We've changed the fuel pump, pressure regulator, gas cap, and had a tune up and the pressure is still building...What else can it be?
One that you have to manually pump the forarm up to build enough pressure in the air tank to fire the gun.
Yes, any pressure or HPA tank on an FEP quest will work. It can not run on Co2.
if tank is pressurizing, clean the fuel tank capthses are supposed to be vented to eliminate pressurizingif that doesnt work, buy a new vented capcheck your evap system.
Physical size of a tank is irrelevant to it's pressure rating.
