hey guys not to steal the topic but i disconnected the canister vac line from my edelbrock and i have noticed when i shut the motor off small air bubbles coming up through my fuel filter ("see through one") and am wondering if that is going to hurt anything, also if you use a vented cap should you remove the trap flap from the fuel cap area? just wondering if that would help the pressure get out of the tank

This is a different topic, so I have moved it to it's own thread.

(TGO policy is to keep threads to the originator's topic.)

The bubbles are vaporizing fuel. Not exactly a desirable condition, can lead to hard starting after sitting hot.

The "trap flap", as you call it, is carryover from the days of leaded fuel. When unleaded fuels were required starting in 1975 in cars with catalytic converters, they put a "restrictor" in the fuel fill to keep a leaded gas nozzle from fitting in the tank, and that little flap to keep people from trying to just pour it into the filler. It has no effect whatsoever on tank venting.

thanks five 7

so what type of vented cap should i get

My recommendation would be to keep the stock vapor canister and unvented fuel cap.
