The Pantera won't suck gas from the pump to the carb, the pump is leaking past the seals, and is it time for new lines? What should I do?
It starts fine one day then this happens! Why?
Thanks

pump rebuild kits are pretty cheap, check the compression on the cylinder that drives the pump if the fuel lines are crisp replace them and oil lines

Kinda sounds like you have a dry rot thing goin' on, or possibly the ethanol eating away at the old lines and gaskets and such. Time to start replacing it all. Run premium fuel when ya can to at least remove one variable.

I have 130 pounds of compression and the lines are extremely stiff! Ok So I'll replace the, but what about the carb?

I think I really screwed up the last time I cleaned one, I just sprayed cleaner through every hole, and blew it out, then did the same with every jet.

Prime the engine and it should finish the pumping with it running.
