Fuel Bowl Drain Valve Assembly
Complete with screws
This is the entire Fuel Bowl Drain assembly that fits the 99-03 Ford 7.3L diesel. The 2 main bowl sealing Buna-N o-rings have been removed and you have the choice of which type of Viton or Fluorosilicone o-rings to replace them with (Choose type of o-ring material at the bottom of this page.)
If you do not have the time right now to rebuild your drain valve or if you are one of the unlucky few that has a damaged drain valve, this is your solution for a long lasting repair and not have to use the poor performing Buna-N o-rings that the factory valves force upon you. If your drain valve is still in great shape, order a set of o-rings and rebuild yours as a spare.
Select the type of compound from the drop down at the bottom of the page.
Differences between the black Viton (A), Brown Viton (B) or the Blue Fluorosilicone fuel drain o-rings sold on this page:
- The black Viton o-rings are polymerized from two monomers, vinylidene fluoride and hexafluoropropylene (Viton (A).
- The brown Viton o-rings are polymerized from three monomers, vinylidene fluoride, hexafluoropropylene and tetrafluoroethylene. The terpolymer blend of Viton has shown to have additional resistance to fuel permeation ans swell when used with ULSD and BioDiesel than standard Viton (A).
- The Blue Fluorosilicone has a much wider temperature range than Viton (A) or Viton (B) and is widely used in extream environmental conditions. They will stay flexible in artic conditions down to -70º F.
