Leaky diesel heater

[AmzngGrace]

So, is it too much to expect a metal to metal screw on my diesel heater to NOT leak? I guess I can tighten it a little more but then I run the chance of stripping it. Is this common? Any other thoughts?

you could try some pipe thread sealant. but you have to remove the screw to do that.

Steel to Steel metal to metal is rather dependent on nicely cut threads. I rely on teflon tape, others prefer thread sealant, but yes, it is too much to expect.

I'm struggling to figure where that screw is exactly... Is this a webasto/eberspacher/Chinese heater? Or something else entirely?

It is something from the 70’s like Dickinson. It is the run into the heater after the regulator. Yes the pic is sideways.

That's a Dickinson Antarctic.We have the same one. Using Dickinson parts, we've had no issue with metal fittings. Check the manual out:

BUT: your setup seems a bit different; where is the oil metering valve (sometimes called the carburetor... but this incorrect as no air mixed wirh fuel)? Normally Valve in front, with fuel pipe from valve entering the centre underneath the heater.

Perhaps Dickinson was different in the 70s (ours is 80s).

People at Dickinson are very helpful. Contact them.
