suburban tow truck fuel issue

Jack McCarthy · 10-18-2011, 11:29 PM

tank has been off 3 times never notice any dirt, or anything else in it. sock is gone just tube with screen over it with hose clamp holding it on. cap has been drilled to vent. lines are now routed outside frame rail up over inner fender and insulated everywhere under hood...

was wondering about drilling hole in bottom of tank for pickup like a fuel cell... oem always had top exit for safety ??

thanks, keep coming with ideas !

Sounds like a condition caused by heat is percolating the gas,either in the line or engine compartment.Checked condition of fuel filter?
You can try refridge line sleeves near hot areas in fuel lines are.
Just some guesses from a two left handed psuedo mechanic.
