I replaced the leaky fuel tank on my '71 B last weekend with one of the
non-vented pre-'70 type. I also replaced the older style fuel neck and
vented gas cap, so in theory everything should be OK. If the car is cold
(i.e. not started for awhile...like overnight), it starts right up and runs
great. It will the continue to run fine for ~20 minutes or so, when it will
begin to stutter, and then die within 5 minutes. It seems if I leave the
bonnet up, the car will run longer (maybe 30 minutes or longer) before it
dies. At this point, the car will not restart unless I wait for at least 1-2
hours for it to cool down. The temp gauge in the car reads in the N range,
and the engine is getting fuel. When trying to start the car when it has
died, the fuel pump acts kind of crazy. It will at times pump like mad (many
clicks in short succession), and at other times act normally (a click every
second or two). The fuel pump does this if I am cranking or just have the
ignition on. I can smell gas at this point, but I cannot see it leaking from
anywhere (engine bay or from the lines or tank). Now it has been 90 degrees
around here of late, and it was much cooler before I replaced the fuel tank
when the car ran fine. I briefly had this problem last summer, and when I
replaced a suspect ignition coil, the problem went away. I guess the
ignition coil wasn't the problem after all. Any ideas?
