Fuel, Oil and Air Filters for 1983 - 1994 Ford 6.9L & 7.3L IDI
We carry all the fuel filters and supplies that you need to keep your trusty 6.9L and 7.3L IDI trucks on the road.
A common problem with the Ford 6.9L and 7.3L IDI engines is hard starting due to air in the fuel supply lines. Replacing the filter o-rings whenever you replace the fuel filter is important, but the rubber grommets on the fuel supply line leading from the filter head to the fuel pump can also cause problems, so you might want to replace those as well. Those are included in the pump installation kit that can also be found on this page. The heater o-ring located at the top of the filter assembly is also prone to leaking. You can purchase the heater o-ring (p/n E8TZ-9K342-A) or the entire heater (p/n F2TZ-9J294-A) from your local Ford dealer. Air in the fuel supply line can also be caused by a defective fuel supply pump.
