Fuel Cap

[toddshotrods]

I can definitely vouch for the need for some kind of venting for the fuel tank. I had inadvertently set mine up with a non vented cap and both other "holes" preoccupied. It would run for a bout a mile and stop. I thought I had a pin hole leak in the main fuel line so when I pulled a rubber section near the tank to replace the old steel line I got hosed! It was literally spraying gas like there was a pump in the tank forcing it out! I had to hold my thumb on it and holler for my dad to open the cap. A big whoosh when he did and the pressure on my thumb stopped immediately.

I replaced the non vented cap with a newer style vented cap and she runs great.
