I have a 86 ta, that was a carb 305 went to 350 changed the fuel pump to a holley (mech) that has no return line. i tried to plug off the extra line and it kept sucking the carb dry, if i left it open then gas would pour on to the headers and that is not kool. ne suggestions would be appreciated.

 

What do you mean by "sucking the carb dry"?

 

the carb will run dry like vapor lock but its not

 

When does it happen? While it's running? After it's stopped?

 

usually after driving it for about 15 minutes, I tried to take off the cap to try to get a gravity feed thing goin but no dice. it wont do it if i am just idling or running only when im driving.

 

I have blown a head gasket or at least i hope so, so while the car is down i think im just gonna run a new fuel system. thanx for the help neways.

 

Well, I would have said it sounds more like there's a problem with your new pump than the return line.
