Fuel Heater O-rings for all 7.3L IDI Diesels
Replacement o-rings for the fuel filter housing (fuel bowl) heating element on all 7.3L diesels. Early style fuel bowl heaters require (2) o-rings to seal against the fuel filter housing, whereas new style heating elements only require (1) o-ring. This is a set of (3) o-rings that services either style.
Fuel leaks due to a bad heating element o-ring are extremely common on 7.3L IDI diesels. Note that the 6.9L IDI does not have a heating element in the fuel filter housing.
- Viton o-rings offer superior resilience against thermal and chemical degradation
- (3) o-ring set services both early and new style fuel bowl heating elements
