On hot days (110 or hotter), the fuel in the tank starts to bubble by the time it flows thru the fuel filter (clear, ziptied in engine bay at the AC metal line). I have an inline electric fuel pump mounted in front of the rear pass. side tire. So not a mech pump issue. Also the gas seems to evaporate when i let the truck sit for a few days. i lost about 2 gallons after not driving it it was 112 outside. I have had many other older vehicles, a carbed converted 97 burb gmt400, and they never had this issue, Prior to buying this burb in 2015 i had never even heard of this being a possibility.
Is my tank itself gettin too warm from the outside temp? hot pavement alone? the dual exhaust pipes that come str8 back emitting too much heat?? What can be done, as im considering pulling a 42 gallon tank (from a 95 burb) and swapping it as i only have the 31 gal tank.
