A couple of places to check for fuel blockage. I have had to pull the fuel filter, bracket and all to clean it out completely to insure fuel could get that far. I then left the line going to the fuel pump unhooked at the filter. I placed a funnel with a short piece of hose on the on the other end where it hooked into the fuel pump and filled the funnel with Stabil. It took a couple of days but pretty soon that varnish build up in the steel line was dissolved. I could pore Stabil in the line and it would run out quickly.
Also there is a rubber line going from the pick up from the tank going to the fuel filter, mine was blocked solid, (low point) so replacing that was necessary.
