Gas Cap

Dennis Kelley · #1 (**permalink**) 10-08-2004, 05:04 PM

Hey guys,

I shortened the gas vent hose on the car and it doesn't seem to have helped. I noticed that my cap is not a vented type and even with the cap off and the leman cap closed there is no way for air to get into the tank. It feels like my car is running out of gas after driving about 15 miles. If I open the cap It runs better. I just wonder what everyone elses cap is vented or not and how does air get into the system through the leman car?

Thanks guys.

TTT,

I suppose no one with a BDR has a gas cap on their car?

Should read CAP NOT CAR.

The typical LeMans cap is not supposed to be vented.

But there should be a vent on the tank itself, or on the fuel line bulkhead on the tank.

The bulkhead on the tank should have; fuel line out (3/8"), tank fuel gauge connection, fuel line return (5/16"), and a vent line (5/16", or 3/8"). If this line is plugged, unplug it. To prevent debris from getting into the tank, connect it to a small fuel filter, then terminate the vent line in some obscure place (on top of the tank, or in a fenderwell) that won't let water in. I used a small check valve in the line to just let air in.
