ArdWrknTrk Posted May 8, 2023 Share Posted May 8, 2023 I found Dorman 800-013 as having two 5/16" and two 3/8" o-rings. But it says for GM vehicles. However, this thread on the Crown Vic site says they are right for those vehicles. And when I was researching the fuel fittings I found that both Ford and GM used the same ones. I'm not sure, as the listing is for O-ring ID while the ones in question need to go over the hose end which has 3/8" ID, plus they don't mention the cross section... But as usual their descriptions are ambiguous. Viton is definitely the proper material I suppose it's worth a shot. I just hate buying things 2 or 3 times to get the right part. At that point I'd rather get a whole kit than muck about with waiting and shattered expectations. Link to comment Share on other sites More sharing options...

Please check it out and let me know.. That would be a huge saving. Thanks, Charles Link to comment Share on other sites More sharing options...

C.Jett Posted May 10, 2023 Author Share Posted May 10, 2023 I've not replaced the o-rings. And looking and playing with this one I don't really see a way to get them out easily. Gary, great photo, I believe your o’rings are still good but mine are so flat that they blend-in with the fitting , didn’t see them until magnifying them. Took awhile to get them out with a pick. It took even longer to replace them. My “ROCK” aka my wife, took over, (she can see better), finished them up. O’rings are from Graingers Item #1BYB7 O’Ring,Dash 012, Viton, 0.07 in. Since I have three port selector valve, I Only need the 3/8. Link to comment Share on other sites More sharing options...

Need to add that, if you have more money than time, buy the repair kit. That way there will be no dirty words. Link to comment Share on other sites More sharing options...

However, this thread on the Crown Vic site says they are right for those vehicles. And when I was researching the fuel fittings I found that both Ford and GM used the same ones. Gary, I decided to chuck the factory fuel lines due to crazy prices and complications. Went with 5/16 x 6’ steel fuel line, cut flares and nuts off, installed in frame original holders behind front fuel tank. Ran short 5/16 hose to rear tank and very short hose to filter and selector valve then 5/16 to fuel pump. 6’ steel line was $16, hose was $16. You can find these parts most anywhere. No complications! Photos later. Link to comment Share on other sites More sharing options...
