Pinhole propane leak to oven

The other day I decided to bake some cornbread and I noticed that a small "flame" was underneath my stovetop when I turned on the oven. It appears that the feed line to the oven that goes through the regulator has a miniscule small pinhole leak in it.

So what are my repair options? Do I buy a new hose or is there a heat resistant tape that I can use to patch the hole? JB Weld? Braze the hole?

Inquiring minds want to know.

Thanks

Usually there is a copper line coming into the stove. Is it the copper supply line or the plumbing in the stove itself. You can solder the hole or better yet replace the bad section. Why did it fail in the first place is the question that I would ask? The pressure on these lines is almost nothing. You want to make sure the line is purged before exposing it to flame. I would replace the whole section from the T below the trailer belly skin up to the stove. The extra thickness of pipe is there to make sure you don't have any holes and has nothing to do with the pressure it is under. Aquarium hose will hold the pressure but it does not take much to put a hole in it or cut it.

The pressure is very low, and you also might just consider epoxy to coat it, especially if it is aluminum tube, not copper, which I have seen on many ovens built over the years.

It's kinda rare to find a pinhole that is the only issue. Most of the time, I've found out that THE pin hole is actually the FIRST pin hole to perforate.

Folks here on the forum are pretty good about offering parts from stuff, can you post the make of your stove and some photos? You might get an offer to send you a replacement part.

The proper way to deal with it is to replace it.

You can get aluminum line from appliance parts places.

A photo would help us figure out what you need.

Here is the hole

The hose is the one going to the oven and its aluminum. it appears to be a small rub hole in the bottom of the hose from rubbing on the oven chassis.

I'm trying to post a picture of the tube but I need to upload it first.

Its a Magic Chef from 1975 with 4 burner.

Then before you fix the hole, you need to fix what caused the hole, or it will happen again. A rubber grommet to pad the edges of the hole where the propane line comes through would be just the ticket. Automotive supply houses are a good source of rubber grommets that should work; they're used where wiring bundles have to penetrate a car's firewall and other sheet metal.

I don't remember any aluminum tubing on mine. Can you not just replace with copper and pad the new pipe? I use rubber hose around the line where it goes through sheet metal. You slit it with a razor blade and wrap it around the tube.
