| what is stock fuel capacity in a '78 pig
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

| The 23.8g capacity is for earlier models only. I'm not sure what year, maybe 73? | |

| 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.

| 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.

| ?!?
Can't you just pull the cap to equalize pressure?
Check your fuel return line, and vent tubes before you go drilling holes... | |

| maybe you have an unvented fuel cap or a vented one with a nonworking vent..try changing it or driving with it loosely fastened.. | |
