title says it all. been having fuel issues. keep running out of fuel at 3/4 of a tank. i've heard about the return line and supply being hooked up backwards...
tank is full and the sight glass is empty. also p.o. installed a new fuel pump.
??????
i think i'll take the fuel pump apart.
thanks for reading

In the Wiki section I'm reading 23.8 gals for da pigs
 
you can see fuel in the fill pipe, and i've had the fuel level sender out to fix it and could see the tank was mostly full.
 
Provided from the Canadian Toyota brochure for the 1978 55 - Fuel Tank: 82 litres -18 gallons.
 
so i decided to see if i could find the trouble... i openned to fuel cap and about a litre of fuel gushed out before i got the cap back on.
some how it must be getting vapor locked. has anyone experienced this before?
 
Yep. The way my 69 pig came, after some wheeling and off camber stuff, gas would get forced out pretty good. it was just incorrectly hooked up, I mean rigged up, tank vent stuff. I replaced the stock set up and installed a vapor collector and charcoal canister from a later vehicle. Problem solved.
 
i'm gonna try using compressed air and blow out the lines. i can only drive for about 5 minutes before it dies on me. then i have to take the level sender out to get the tank to equilize pressure.
thought about drilling a hole in the fuel level sender and silver soldiering a tube in it and running another vent line.:wrench:
 
maybe you have an unvented fuel cap or a vented one with a nonworking vent..try changing it or driving with it loosely fastened..
