If you are having problems with fuel delivery on your 80's or 90's Bronco or truck check the fuel filter/recirculater. It has two small rubber valves that stops working if they dry out. Ford here in Lake Havasu wants 250.00 for that part. I took that part over to my friend that works at Carquest, He took some measurements and handed me 2 can style filters for 17.00 and I've been driving without any problems for two years now. The filter numbers are R86555/BG7000/R86595 and R86484/BG4702 RFI.
