I finally finished hooking up my propane kit last night and got the engine running but it died out after about 30 seconds and I could not get it restarted on propane.

I have a 305 with an Impco 300A mounted on top of a quadrajet. The 300A is fed via an Impco Model E regulator, which in turn is fed from an Impco vacuum actuated fuel lock.

If I force vacuum to the fuel lock and pull the low pressure feed off the 300A I can see and hear the propane vapor.

So, I guess my question is has anyone else gone through this? Could it strictly be a timing issue? Vacuum? Tips? Anybody?

use a match to find any leaks.....

hey, good idea. I'll park it in the garage and leave the gas on for a while first....

Propane how do you see propane it is a clear gas, it smells only because man put the smell in propane.

Sounds like you have a vaccuum leak. I aggree light a match to help find the leaks.

hey dipstick i added your joke to my comment as a joke.

As for the problem at hand it sounds like it is a vaccuum leak. If the system is vaccuumm operated, and the line is primed and then when the priming is gone the engine dies.

got ya.....would u reallt put me into some oil or fluid to check the level though???

traced the problem back to the fitting on the lp tank. I drilled the opening wider and now everything is running smoothly.
