Chuck,
The plastic lined tubing is normally connected via a hose barb fitting. i.e. no crimping. If you have a tubing specialty supplier in your area, take the line, connections and all, and see if they have a better/safer setup.

This is what it looked like before the bottom hose gave way. The rubber at the crimp (just below the fitting to the fuel filter) just popped off. ![soapbox](https://rennlist.com/forums/graemlins/soapbox.gif)
Will be taking pics and removing today. Dennis, I'll look around for the hose you are describing. Problem was, when I had the lines rebuilt a couple years ago, NO ONE in DFW would touch fuel or brake lines. Must have called about 20 places.

Wow, that looks like the insides of a new car! Thanks a lot for the pics. I'm trying to recreate this lot. The brackets that are holding this lot in place are very rusted on my '78. I've had all the fuel lines (also the long one, including the curved metal parts) recreated by a hydraulics firm. It should stand up to 180 bars they say.....

Ad,
When i replaced everything, I did not have any rust as the car has pretty much been garaged it's whole life. But it did have 30 years worth of crud, mud, grease, road gunk, etc. All it took was replacing parts and then I scrubbed everyting w Simple Green. It all came off pretty easy.
I think after many years, dirt actually becomes a preservative!

Chuck,
The side tension probably pulled the compression connection loose. A hosebarb fitting and adjustment of the loop should fix it. BTW if the diaphram of the accumulator ever gives out the fitting on top will most likely go bad. If you have a Graingers near by, they should have the correct hosebarbs.

Couple things,
Dennis the part that came apart is the connection at the bottom of the fuel filt. That 1 ft hose connects from there and goes straight down to the hard line (and connects) that goes to the front of the car. No tension on that, so that's why I'm scratching my head on that one.
Ad, as Dennis said, the big loop comes down off the expansion tank that is over the wheel well. It comes down behind the fuel accumulator/filter assembly, loops back up and goes to check valve. Next hose comes off the check valve, loops up and back behind the fuel accumulator than down and connects to hard line via a hose clamp (just out of sight under the pic) I did not follow the hard line, but it goes either to the carcoal filter (eventually to the front of the car) or as Dennis said, back to the gauge sending unit at the top of the tank.(cant remember, did not have time to follow it)
(I can take time to see where it goes, but headed to work here in a minute)
Reason the loop is so big is probably to avoid kinks. I basically took pics before I removed all componants and put everything back per the way the factory had it.

Chuck,
The picture obscures where the bottom hose is connected to the fitting but it appears to be a simple crimp connection. That should definitely be replaced with a hosebarb fitting. It may be alright for a 30 psi EFI but not a 95 psi CIS pump pressure.

Could anyone (CHuck ?) please explain how the fuel filter is tied to the car? The bottom bracket that is welded on my car is completely rusted. Is the band around the filter tied to the bracket? The checkvalve seems to be mounted in a hole on the same bracket. From the remains I cannot see how the fuel filter should be mounted. Thanks...
