Fuel line for Diesel heaters

Just an FYI if you have a vevor (etc) diesel heater I found certified fuel rated hose 3/32" (2.38mm) ID x 3/16"OD, 100psi (690kPl, 9bar)) at Home Debit, . It's in the plumbing department beside the white nylon hose. It's easier to bend than the white nylon hose and it won't kink, but the material is far less compressible than the cheap soft hose that come with most diesel heaters. Made by Canada Tubing Products, part # SUFD10, it was less than $10 for 10' (3m). I tried heating the line to see if it would slip on, it won't, so you will still have to get attach the same way as in John McK's excellent YT videos.

 

I think I used the same size to repair a Waterpik a few years ago lol. But it is also available with 7/64 and 1/8 ID:

I though it might be too small but 2mm ID is what is said in this vid.
Also I measured the fuel pipe on my new 8K (really 5K) heater and it is 2mm ID.

I also took 1m section of the tube, cut some slots into the one end, slid a section of electricians fish tape (wire) into it, affixed the red tube from a Fluid Film spray can on the other end and then used the spray nozzle on a can of PB Surface Shield. This easily feed into the drain and/or bump stop holes of the doors, pushed it in straight in as far as it would go, started the spray. It takes a few seconds to start to spray but when it does you can really hear it transition from air to spray and you then slowly pull out the tubes spraying as you go. I do have a more pro undercoating gun with attachments, but with this small tube and can method I can get into small body drain holes with no drilling. The wire is so the tube stays straight when you feed it through a hole.

So far I've only done two doors and will post the results of the complete rust proofing job when I'm done.
