[AT] Tractor hauler question.

[Andy Glines]

Farmer, is it a Carb or a throttle body injection?  Fuel injection often has presurized fuel tanks.  If it is a carb, did the truck come with a carb originally?  I would tink that a carbureted engine would use a fuel tank with a vent.  Maybe the fuel system has been altered since new.  Also, make sure that the tank doesn't have a vent that is clogged up.  The vent may be in the cap or somewhere else.> 11. Tractor hauler question. (Francis Robinson)> My old 1983 Ford F150 farm pickup (carbed 302 with auto/overdrive) that seldom is driven more than a few miles at a time except when pulling the gypsy wagon (usually hauling my CUB) uses a fair amount of fuel. Of course even empty the gypsy wagon is a little like pulling a parachute. The thing I noticed today was that it had a substantial amount of pressure in the fuel tank when I stopped for gas today coming home from Portland. I know that some of the later vehicles do that but I thought that it was too old for that. I don't recall my other 1983 (300-6) F150 ever doing that. I rarely stop for gas on trips with it except at starting out for the day so I never had occasion to notice it before. I was wondering if all of that pressure was maybe pushing too much fuel past the float valve? It seemed a lot higher than I had seen on other tanks with pressure build-up. Is a high pressure normal on that age and configuration or do I need a cap that is vented both directions?
