1985 F150 4.9 L fuel lines

Can you reuse fuel lines to three port selected valve by installing new retainers?

If you are talking about the Nylon lines, then yes you can. And if you don't break the retainers you won't need new ones.

Thanks Gary, they are nylon but the retainers crumbled and I will source new ones. I read some where there were o’rings also, did not find any on my lines. Does it use o’rings ?

The o-rings are down inside the connector and are hard to see. I always wipe the metal or Nylon fitting clean before inserting it to make sure it doesn't damage the o-ring.

Thanks Gary, do I replace the o’rings ? 5/16 or3/8 ? Sorry for all the questions but all my tools and equipment are in a storage trailer several miles away. At present, I’m am working in my driveway. It is what it is. So please bear with me. I value your advice and help very much, many thanks. Charles

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.

Ford seemed to use 3/8 for supply and 5/16" for return.
Dorman offers these in their HELP! line as 800-004 for black (3/8") or 800-003 white/translucent (5/16")

I suggest a little grease or Vaseline on the fitting for easier insertion, so it slips past the O-rings without pulling or rolling them out of place.

Re: 1985 F150 4.9 L fuel lines

Thanks Jim, mine is three port so 3/8 it is. Do you have a # or size for o’ring. Mine are so flat that they are almost invisiable. I use silicone spray most of the time. Charles

I'm afraid I don't have a part # for the O-rings.
Perhaps someone on the forum does?

Dorman also sells the replacement fittings. I wonder if they show a size in some kind of documentation?

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.

Jim, as near as I can tell, these match. Grainger o’ring 012 3/8 ID -1/2 OD. Item# 1byb7. Please check it out and let me know.. That would be a huge saving. Thanks, Charles

Given your picture I'd say the Grainger ones are the correct size.
It's really hard to know for certain over the Internet.

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.

Re: 1985 F150 4.9 L fuel lines

Need to add that, if you have more money than time, buy the repair kit. That way there will be no dirty words.

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.

Re: 1985 F150 4.9 L fuel lines

All is 5/16.
