How to replace EVAP line from gas tank?
I went to Lowe’s and got some tubing that I could fit in the white block. I had to drill it out. I then slide the tube in and connected it to the hose. I used RTV around the tube going into the white block. That white piece is part of the gas tank so you have to replace the tank.
How does the fuel tank EVAP system work?
Fuel tank pressure monitor (1998 and1999 model) The EVAP control system is a system which utilizes the intake manifold vacuum to draw the evaporative emissions into the intake manifold and mix then in with the intake air. The ECM controls a duty−cycle type VSV (vacuum switching valve) to purge the evaporative emissions from the charcoal canister.
What happens if you disconnected the EVAP canister?
On cars that I remove all the stock stuff and put a carbed 350 in without any emission stuff its common that people just put a little breather type filter on the end of that evap line out of the gas tank, either up front or on the frame rail or anywhere it wont get water in it. Plugging it would be bad. You want to let it breathe.
How is the VSV used in the EVAP system?
VSV (vacuum switching valve) to purge the evaporative emissions from the charcoal canister. The ECM uses the vapor pressure sensor to detect malfunctions in the evaporative emissions (EVAP) sys- tem.

How to remove the EVAP canister from a car?
Pull the box out and down towards the wheel well. Now you should be able to disconnect the hose that leads to the fuel tank ( Hint: it’s corrugated and a right pain to get off) I used needle nose pliers to compress the clips. You can now disconnect the third hose (the air intake) from the frame on the inboard side of the vehicle.
Where does the vent line go on an EVAP?
You can eliminate the canister and associated hardware, but you’ll still need the vent line. To make it roll over proof, the vent line should be routed UP from the tank, probably about 1-2 feet, then routed down to below the tank bottom (by a foot or more if possible).
How does an EVAP tank roll over proof?
To make it roll over proof, the vent line should be routed UP from the tank, probably about 1-2 feet, then routed down to below the tank bottom (by a foot or more if possible). This prevents gas from escaping in most roll over situations. Because liquids will always flow to a equal level!
