Lightbulb Fuel line routing

So im trying to run my fuel lines and delete the evap can at the same time. Now i have found this picture..







So my question would be.. Can i just run the return line from the engine to the green port on the fuel pump itself? Has anyone else done it this way. Im not worried about the ses light. So any ideas?

Thats my picture I made several years ago. I'm pretty damn sure you can do what you want but you might get a error code.

Re: Fuel line routing

What I mean is, mechnically I think it would be fine but electronically you might get a code. There is a plug on the evap purge solenoid. That might produce the code if its removed.

Finally a response..


But yea the pic was one of the better sources i found while searching. That and a thread djd posted. I have come to the conclusion that ill just remove the canister all together. Rerun the lines and just put a little vent/filter were the canister lines would of ran. Hopefully tht'll work and i wont get all the built up pressure in the tank every one talks about.

Re: Fuel line routing

Actually you will get tremendous vacuum in the tank, not pressure, if you were to just connect the line from the engine right to the tank, and thats because you are pumping all the fuel out of the tank and burning it up, and youre not allowing anything into the tank to replace it. The Evap system allows air back into the tank so it doesnt build vacuum, and does so without allowing fumes to escape. If you put the vent on you will be fine but youll def throw a code if youre 95+.

Re: Fuel line routing

If there was a vacuum in the tank, how could anything, especially fumes, exit the tank? There will be no vacuum because the gas cap will allow air in to displace the gasoline. The cap also has a pressure venting valve that will blow off if the tank sees more than a few PSI, needed if the evap systm totally clogs.
