i finally got my car up and running and took it for a test run. car runs great for about 15-20 minuts then the pressure in the tank gets so high the pump can't pump any fuel.as soon as it dies,if i take the cap off and let the pressure out the fuel pressure comes right back up and the car starts and runs great until the next time it builds up. i got a new gas cap (vented) today but haven't had the chance to go out and drive it yet. should this new cap solve the problem? the stock pickup has 2 lines coming off it and the smaller of the 2 is capped off from the factory. if the cap does not solve it can i run a line off the pickup for a vent? thanks guys.

If you are developing vacuum in the tank then a vented cap will fix the prob.
If you are developing pressure in the tank then cap may be OK too but there may be some emissions piping from tank to engine missing.

thanks for the reply. i found the problem. i pulled the tank yesterday and the vent tube for the tank was blocked up. cleared it and presto! it works now.
