Installing the nylon original stuff would be fun...... especially still on the truck.

Reason I asked for pics of the fuel line connection is, they are different over the years. So the rail I have sitting out in the barn, may not work for your fuel line. You seem to have the situation in hand though, so, watch it, see how it behaves. If it makes ya too nervous, I still have the fuel rail.....

If I do, do the nylon fuel hose, I will remove the fuel rail from the truck, that will make the job much simpler.
And thanks for the offer of the fuel rail, I'll keep that in mind.

one would certainly hope.

I don't know how the stuff is put on at the factory.... if its heated to soften it up, and pressed on, pressed on cold I think would be rather difficult by hand...... crimped? Hhhmmm..... wonder if they make dies for the crimping tool that small..... (I've done plumbing with plastic pipe and crimp-seals, works awesome, is super easy, and is rated for much higher pressures than our fuel systems would ever see......)

Thanks for the photos! Looks like a very nice repair job. You should be good for quite some time, as long as you used fuel injection style fuel hose.

Yes, I used fuel Injection hose rated for 100 PSI (6.9 BAR) working pressure.
As I understand it the fuel injection system should be in the 50 PSI range give or take about 4 PSI...... so it could be 46 to 54 PSI.

When I was a mechanic at a Dodge stealership what they did was removed the house used basically heat shrink with adhesive put that over the hole before getting it up. That was the fix and it was only $899 just some thought I have the technical term for the stuff written down.

Default Same issue..

Tried replacing crossover hose, but no joy. I am thinking I just need to replace the rail. When you mention "most other year" - which should I go up to (would like as late as possible)?

94 to 96 had the same connection, 97 was an odd ball piece of plastic that should be avoided at all costs, then 98 and newer took a different connection at the rail (IIRC).
If you go with the newer style, you will need the flex hose that goes from the hard line at the frame to the fuel rails.
Hope this jumble of info is helpful. Been driving all day and my thoughts aren't very coherent.

Any except 97. But as stated you will need the flex line. It it held in place with 2 bell housing bolts and a connection on the driver's side frame right where the frame goes straight. But you do need a fuel rail tool to disconnect it
