Hey all, had to replace the flex hoses (to fuel filter, overflow from pump) coming from the fuel tank to the hard lines. One had sprung a leak, replaced both truck ran fine prior to replacement, minus the leak. She started right up and then ran out of fuel. Switched hoses to make sure that wasn't the issue. Still wouldn't start. Poured a little gas in the carb, fired right up and kept going. Parked her for the night no bueno the next day. Tried again today same result, popped the hood, and am now leaking from the flex hose into the fuel filter. I guess it is time to change that now. Pretty sure the check valve in the filter is now shut tight and why I am not getting any fuel to the carb. Does anyone have a fuel system diagram? I have both factory manuals for my 81 and can't find one. I want to make sure I have the flow of the lines correct.
