While waiting for some replacement parts for this project, I've been disassembling and inspecting.
I wondered why there was a four inch fuel hose clamped just downstream from the tank fitting along with a one inch piece clamped just at the tank compression fitting. At first, I figured someone had installed, and later removed, a fuel filter. But, not.
You guessed it. In order to fix a cracked fuel line right after the fitting, the DPO cut the line to insert the small piece of fuel hose and placed a hose clamp perfectly enough over the crack so that it sealed. Then, he clamped a mending hose over the cut line. Judging from the crackling in the rubber, it was there for several years!? And I had filled the tank with fresh gas and left it in garage while on vacation for three weeks. Fortunately, it held. That could have been TWO DPOs!
Should I enter this repair in the library?

Maybe the PO needed it fixed now, so did that temporary repair. When the repair worked the temporary become longer and longer.

When I was about 100 miles into a 600 mile trip in a Ford Taurus, I ran over a piece of metal on the interstate in a Ford Taurus. The piece flipped up and cut through the fuel line under the car (and ripped out the sidewall of a tire!).
I pulled the car to the closest civilization, a very small Arkansas town. The only car dealer in town was a Chrysler dealer but they agreed to see if they could fix the fuel line.
To make an all too long story short, they couldn't fix it and I ended up digging around in my tool bag and finding a piece of fuel hose and a couple of small hose clamps. They refused to do a temporary repair, but they allowed me to work on the car on their lift.
I patched the cut line and off we went. The only time it leaked was immediately after the engine was turned off, when the fuel pressure was the highest. I replaced the fuel line from front to back when I got home.
Maybe something like that happened to the PO of your car.

Hey, Bob! How are you? But you used two clamps! Any of us would have done that! This was one clamp!
The best part that got me down there in the first place was that the line leaving the aftermarket pump bolted to the SU bracket did not line up with the fuel pipe going to carbs. So, he bent a piece of fuel hose into two reverse 90 degree elbows to make the connection! I didn't photo that one, but I was surprised the hose didn't split!
Anyway, a full rehab of fuel lines and pump is pending!

Robert, I was struggling to remember a name until I saw yours. This reminds me of the Red Green show some years ago out of Canada. Only, he would have used a chainsaw and a bulldozer to cut and bend the line! "If the women don't find you handsome, at least they'll find you handy!"

Let me start off by saying I grew up in a rather cosmopolitan area, Tampa Florida. I had access to Sears ,Wards, Western Auto, and even a Beck-Arnley store dedicated to crazy foreign cars. But moved to a rural area of Easter Oregon 25 years ago this June. When I first moved here I was introduced to the world of "backwoods " repair jobs done on numerous cars, truck , tractors, generators and previous home repair jobs. I was always impressed by what someone could dream up to fix something when they did not have the time, correct part or simply brains to do the job correctly ! After speaking with a lot of people who grew up in the area , (farmers ranchers loggers) I began to realize just how inventive folks became. Now a days I stop for a moment before disparaging someone over a not so normal repair attempt, and marvel at their ingenuity. Fuel lines and fittings do not fall under above category.

The thing that bothers me about it (other than only one clamp of course) is that when the metal line splits, there is nothing keeping the hose together. So it isn't really a proper patch. If it were a puncture further along the line then this "fix" could be left as permanent. In fact I would intentionally cut the line clean through before putting the hose piece in.

The advantage of your approach would be that there is no risk anymore of a shearing of the metal with the risk of debris entering the fule line. And it will also physically decouple both metal lines from each other, so any body movement will just bend teh rubber hose piece. Be sure to buy the right type of ethanol resistant hose though, there are certification numbers on the right ones
PS My still undamaged metal fuel line tank to pump "sweats" on the banjo bolt junction on the pump. Retightening and new fiber washers never take it fully away. It may have to do with the body movements or not, that's why I contemplate cutting the metal line myself and inserting a short rubber hose. But is it is just about a drop hanging there, so this is very low priority for me.....

Hi Don,
I've had the sweating fibre washers on my Wooly. A bigger problem than with a B, since the pump is in the boot (trunk) and the vapours get through the car. I think that the fibre washers are porous, whether this is a new problem or not I don't know. I removed the banjo fittings and fitted hose tails and rubber hose to the pipe work, no more problems.
The attached article shows how I did my B.
