Vented Gas Cap

Vented Gas Cap
I'm having some gas fume issues in the rear of the car now. Charcoal canister is deleted already. Haven't dropped the tank completely (have the trap door for fuel pump replacements) but don't see any fuel leak (wetness) around the filler neck. Next plan is to cap all the lines for the EVAP and run a vented cap.
Anyone know which caps fits the LT1 tank that's vented?

Just curious as to how a vented gas cap would fix this problem? Thought they were more for releasing pressure when it builds up.
I had a gas smell sometimes on my 89, was a crack in the filler neck. Its a crack or leak somewhere imo.

i actually have the same issue, deleted the canister and left the line hanging in the rear fender. tried a search on summit but couldnt find anything that'd match the OEM style cap.

Again, the lines are all capped at the top of the tank at the sending unit. I don't have any lines hanging loose anymore. Only the fuel line and return remain and the others capped. I don't see any wetness (fuel) at the filler neck when I've looked at it.

I think I made my own problem here. I was running the stock UNVENTED cap which was causing the leak. I simply drilled a very small hole in the cap to releave the pressure until I can get the correct vented cap. I'll see if that works until I can figure out which vented cap for this application.
