'90 302 efi.

truck starts hard... when i get it going i have to keep my foot on the gas, make high rpm's so it won't stall. after a minute or two the truck always dies. my brother in law thinks it's a fuel problem. that its just consuming hte fuel left in the line. but the pump worked good when i changed the filter. i'm thinking it's the pressure regulator. called the parts store started getting prices from 60 to 160$ CAN.

looked on ebay.. there's nothing for ford trucks but they sell a lot of parts for 86-93 5.0 mustangs... will the part work? where else can i order one. lot of places don't like to deliver to canada either
