i've got a '58 apache with a 235 that seems to lose fuel pressure after about 3 miles of running. i've checked all the obvious stuff. pump is delivering pressure, filter is good, lines are not too close to the engine to cause vapor lock. had the carb rebuilt a year ago.
after i got stumped i took it to my local shop and they couldn't find anything. and i trust these guys. i don't think the tank is too rusty, because the fuel is running clean and the filter isn't catching too much gunk. anybody got any ideas?

thanks
