69 Fuel line

[John M.]

Has anyone replaced the fuel line on a 69 with the body on the chassis? When I first looked at it, it looked possible because the line goes on top of the kickup in the frame instead of through it. I just finished the brake lines and now that I'm looking at it again from underneath I'm not so confident. Getting it to the kickup and then up and over looks like a trick.
Thanks

Re: 69 Fuel line

There were some guys in the archives that claim that they could do it without taking the body off. It may be possible if you have a lift. I am not so optimistic. I tried and ended up with a mess with prebent gas lines. I ended taking the body off for other reasons and then changed them out. good luck Joe

Don't tell anybody, but I have seen people put unions in the new supply and return lines. Out of sight in the kickup area, out of mind. Someday when you or the next caretaker takes the body off, all can be made whole again. Just a suggestion.

Agree. Not ideal, but better than doing a body off when you weren't planning to.

Recommend Swagelok or Parker tubing fittings.....not generic hardware store unions etc. The Swagelok and Parker fittings are essentially "bullet-proof" when installed properly. We routinely use in the chemical plants for some nasty chemicals....with no failures. Google the names for where to buy. Probably available from McMaster-Carr or Graingers. I still use our company wholesale supplier for my orders, which is a lot easier for me.

Re: 69 Fuel line

I've got the body off and you have to put the tubing at weird angles to get it through the #2 cross member.

Plus, the lines are not bend properly from the vendors. You have to make the effort to adjust the bends.

I don't see how anyone could do it PROPERLY with the body on.

Yes, using high quality couplings really compromises nothing. Located properly, they can't be easily seen. As far as their integrity is concerned, they're really no different than other fittings which normally exist in the fuel or brake system. If those can be made to seal properly and be durable, then the added couplings will be just the same.

Re: 69 Fuel line

I read that it could be done, and talked with 2 people here who did it. So, I tried. No luck at all - had most of it installed from behind the trans crossover up to ther front and also up into the kickup, and it bent.

So, the orange 72 has a union in each line between the trans crossover and the diagonal just before the kickup. You can't see them unless you know they are there, and the rest of the lines went in moderately well.

As one of those who did it told me, they won't look like factory lines when you're done but they'll be in there. Mine look close - except for the unions.

FYI, I later did the brake lines - much easier.

Re: 69 Fuel line

Thanks for all the replys. I think you saved me from a lot of frustration and time. I'll get the union and go in two pieces.

Just make sure you use a union for double flare type application. You do not want to use any ferrule-type union for low pressure applications (even though for the fuel line it is a low pressure application). The tubing ends MUST be double flared for either brake or fuel lines.

Thanks Joe,
We have all the necessary stuff here at work so I should be ok.

Joe and John:

The tubing ells (90 degree fittings) and straight tubing unions I mentioned above do not require flaring. You simply cut the tubing straight with a tubing cutter or hacksaw and install with straight ends. The Parker and Swagelok fittings I recommended have their own patented internal ferrule connectors and are good up to the burst pressure of the tubing. They are also not very big/large for their tubing size, so they are not obtrusive.

They are available in brass, stainless steel, or whatever you desire (and can pay for $$$).

The Swagelok 3/8" stainless steel fittings are: straight union #SS-600-6 and ell union #SS-600-9. For brass use the prefix B instead of SS. Not certain of the Parker numbers without checking.

These connectors don't leak....period.

Where does one obtain them?

[John M.]

Re: 69 Fuel line

Joe, We have them here and buy them from a Swagelok distributor. If you need just one or two let me know.
We build high temperature, high pressure transducers here.

Thanks for the offer. I don't need any right now, but if I ever do, I'll keep you in mind.

I get mine directly from the local Swagelok distributor: Capitol Valve and Fitting in Belle Chase, Louisiana. However, Swagelok has distributors throughout the USA and world-wide. You can go to their website and check for a distributor near you. www.swagelok.com

Same/similar for Parker fittings. http://www.parker.com/portal/site/PA...%28SS%29&Wtky=

Grainger and McMaster-Carr also carry these, or their equivalent. I think a few other companies are now making and marketing......they state they are Swagelok and/or Parker compatible.
