the hose from my oil pressure gauge is broken. I now wish that linking only the hose is thickened by the pressure. Now I get the gold nut not through the tubing. does anyone know how I get through it again or do I need a new hose which is not expelled, Thanks, sorry for my bad english

You will need a new compression fitting. You can buy them at your parts store or you can get a new line kit. They sell the line kits in plastic and metal.

Thanks for youre reply, i cant heat the old line and put it back on?
Otherwise i will buy a new line

The compression fitting ferrule crushes on the line when tightened, so you can't reuse it. If you buy a new fitting you can repair it and use the old line.

The ferrule is really the only part that you need. It is consumable and can only be used on one line - once it is tightened, it will not come off and cannot be reused on another line.
The nut and the fitting screwed into the engine can be reused.

Google «⅛" compression fitting ferrule».

This may be a good time to switch from nylon to copper tubing, which should be more durable.

Personally, I'd be more worried about that short section of hose from the thermostat housing to the water pump. That doesn't look too healthy, either.

My first thought too

so, what is that OTHER huge horizontal hose and the other smaller hose protected by a piece of old heater hose?

I believe his car runs on propane, hence the extra hoses.

joe_padavano

From his other thread, the car is a 73 D88 with a propane conversion. The smaller horizontal hose looks like the ones coming out of the propane tanks in his trunk, so I'm assuming that's what it's for. The larger radiator-ish hose is a mystery. Hot water heating for the propane carb?

Haha true, i replaced that hose, during that i broke the oil gauge

koen2k

Thats true

thanks Eric, i found one

Jegs and Summit among others sell the line and fittings in a kit. I like copper line vs plastic.

Since that section broke, you can bet it may be waiting to break elsewhere, too. Inside the car would be even worse! I broke the one on my old Ford when changing oil, so I replaced the whole thing. it was over 2 years old anyway - plastic turns brittle over time. Tape the end of the new tubing to the old and just pull it gently through. Use grommets where it is up against holes or such. Do not overtighten the nuts though - easy to do with nylon or thin copper.

I finally received my new kit. the new lock ring fits easily on the wire. I'm afraid if i attach it now wants to slip. Am I wrong?
The hose must not be linked through the left fitting right?

MDchanic

When you tighten the nut, the ferrule will compress against the tubing and become tight, which is why it's called a compression fitting.

The tubing pushes into the base portion as far as it will go, then the nut is tightened, compressing the ferrule.

I'm not sure what you mean by "linked."

And you do have only one ferrule on there, right? It almost looks like two, back-to-back.

Thanks for your answer Eric,
Yes its tight now i figured it out

With linked i mean connected.

there is only one ferrule, i thought the same, but its new, they dont have the old ones back to front
