Connection from oil filter to burner

Hi, I have a leak at the connector of my oil furnace. Previous owner connected the hose from the oil filter to the burner with hose clamps, shown in the attached picture. I made these clamps very tight and oil is still leaking from the end. What is the correct way to attach this hose?

A flare nut should be used so the firematic oil valve should be changed too.

There is a flare nut there. It looks like the orange line is just slid over a short piece of copper pipe. There was probably copper connecting the filter there originally.

I'm not an oil guy so I don't really know what you need there. Grady can probably help.

With that longer taper looks like a compression too me.

Either way..... it would mean the hose is slid over a piece of copper pipe and needs to be changed.

Pete, looks like the plastic shielding for oil line, just needs to be cut back.

Guys, thanks for the response. You are correct, there is a piece of copper pipe ~1.5" long and the orange hose slides over it.

I am unsure what you are proposing as the solution. Are you saying that I cut back the orange hose a little bit and re-attached with hose clamps? That was my initial thought.

Completely wrong no matter where if that is not sleeved oil line. Need sleeved oil line from the tank to burner with flares....... Guess you were right Pete. Get that fixed baseball or you be out.

I sent a PM to my forum partner Grady. He's the oil guy. My specialty is controls and wiring.

If indeed that is coated copper & not just hose slid over a copper stub, I suspect the leak is due to a bad flare. The coating needs to be cut back 3-4", the flare cut off, & the tubing be re-flared with a new flare nut. With coated copper, the clamps should not even be there. It is possible the leak actually originates at the other end & is migrating between the coating & the copper tubing. The purpose of the coating is not only to protect the tubing but to also indicate a leak somewhere.
