What should I do if my fuel tank pressure is too high?
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. I’ll try removing and blowing out the vapor line from the canister to the tank. If no result, then maybe I will try a new gas cap…it was replaced about 5 years ago.
What kind of pressure does a fuel line hose need?
Working pressure is not relevant, but wire-inserted hose can withstand 50-85 psi, depending on diameter. High-pressure fuel hose for clamp-type fuel-injection systems is also available. This fuel hose is SAE 30R9-rated and uses a fluoro elastomer inner liner that will withstand up to 180 psi and 300 degrees.
What does the fuel tank pressure sensor read?
However, when the sensor itself causes a problem, P0452 or a P0453 set for the fuel tank pressure reads low or high respectively. Unfortunately, if the seal fails where the sensor fits into the fuel tank it can also set evaporative emission system leak codes like P0442.
What does OE pressure relief 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. It also permits pressure to escape if the vapor management system malfunctions.

What kind of tubing do you use for fuel line?
Nylon fuel line. Many late-model production cars are now using hard, black nylon tubing with special connectors to attach fuel-feed lines to the gas tank sending unit/fuel pump modules. This gas-resistant nylon tubing can be purchased by the foot or in short sections with the proper ends already attached to one end.
What kind of lines are used for fuel return?
Fuel Return Lines by Fine Lines®. This American-made product is crafted by knowledgeable staff to ensure superior durability and ultimate quality. It was engineered with the highest precision and made using high-tech machinery. Backed… Fuel Filler Hose by Gates®.
Is there a problem with the fuel tank pressure sensor?
Sidebar: The diagnostic steps above cover the most common problems. However, in rare cases you could have a real fuel tank pressure problem. A malfunctioning vent valve or a defective pump that supplies the pressure to the tank for the test can also fail.
Can you blow air through a full fuel tank?
I called Spectra and tech support said the “valve looking object” on the vapor line is actually a screen filter. 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.
What is the Check Engine Light code on a gas tank pressure sensor?
This fuel tank pressure sensor article covers a boatload of General Motors cars and trucks. These automobiles will set a check engine light code in the P0440 range. However, when the sensor itself causes a problem, P0452 or a P0453 set for the fuel tank pressure reads low or high respectively.

What to do if your fuel tank pressure sensor is not working?
If you don’t have an automotive scanner you’ll have to lower the tank and pull the connector off the pressure sensor and test it with a voltmeter. If the voltage reading is either zero or five then it’s possible that you have a wiring problem.
What happens if the fuel pressure regulator fails?
The fuel pressure regulator controls the fuel pressure in the fuel rail. If there is something wrong with the fuel pressure regulator, it can create too low or too high fuel pressure in the rail. It is not very common that this part fails, but it can happen.
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. It also permits pressure to escape if the vapor management system malfunctions.
