Has anyone else experienced problems getting gas to flow from the tank to the fuel pump? I've had this issue before and could not figure a logical reason for it. After going over all the reasons fuel would be blocked and trying every method to gain fuel flow, it would just start flowing right at the brink of frustration. My 67 Polara has a new fuel tank & pickup/sender, all new rubber hose, a good steel line and vented cap but came to me running off a 1 gal gas jug in the engine comp. Car sat for 10 years. I'll get into it next week, just looking for some insite.
