Pretty much what the title says. I will be using the Holley HP management system on my 383. I am wondering what to do with evap system. It would seem easier to eliminate the system then program one of the I/Os to operate the system. Has anyone successfully kept this system with an aftermarket fuel management system? If not did you just swap to a vented gas cap?

 

I removed the evap system, and put a small filter on the tank vent hose.

Do you have any issues with gas fumes collecting under the hood? Or is your filter somewhere else?

 

Mine is vented under hood. No odor whatsoever. I may have it deleated in tune. I forget. It has been six years that way.

 

Nope none. The only issue I have with fumes right now is the crappy summit brain braided AN fuel hose. The stuff doesn't leak but reaks of fuel.
