Keep one on Hand
Noticed my 7.3L was leaking diesel on the driveway. Replaced fuel bowl seals and passenger side fuel line which had a small leak in it. Truck runs great no more leaks.

amazing and easy
If you have a leaking fuel bowl this is a great product I had no problems installing the o rings and now the truck is leak free. Just don't over tighten the fpr I snapped mine in half had to order another one. The whole job is easier to do on the bench than in truck.

Nice!
This is what you need if you have a leak. All the pieces you need. Do yourself a favor and replace all of them and not just the problematic fuel drain. I had multiple seeping. Easy to do.

2003 F-250 fuel bowl rebuilt
getting the fuel bowl out as not bad. Removing and replacing o-rings was well laid out with online instructions.
I was originally only going to replace o-rings on the fuel drain and wound up taking the fuel bowl out and doing all the o-rings and fuel line seals.
the Fluorosilicone Drain Valve O-rings are so much better than viton type so not sure why they offer the lesser quality. :)
the process took a bit longer than expected.. getting the old fuel line seals out especially the left side smaller ones were a bear.. I had a pick and tried to pull them out..
TIP: pull the fuel line seals out BEFORE putting the fuel bowl back in. more space to work
I found grabbing the nut, pulling and twisting like you are trying to pull it off the tube would get the seal out enough past the nut where you could get the pick on it and pull it into.. then you grab one end and pull the varmint out.
overall nice kit.

Straight Forward
Bought this kit to solve my leaking fuel issue. Really easy install, has actual size pictures of each o-ring and where they go to so there is no confusion. Has everything needed including the fuel line sleeves. Could not have asked for a better product or better price. **Please not if you remove the fuel inlet and outlet fittings(optional) you will need a threadlock, Gasoila is recommended and not included in the kit.
Thank you Clay for another great product. -

Good rebuild kit
I bought this kit and upgraded the drain valve o-rings with the blue fluorosilicone o-rings. I was installing the FRX and thought this would be a good time to take the fuel bowl out of the truck engine to clean and rebuild. Good kit. No leaks.
