Ken.
thank you for sharing about reuse of fittings on original fuel lines. I would also like to reuse them but can’t figure out how. Do you screw two female ends onto male/male coupler/union to hold everything rigid then put wrench on collars covering hose? I say this because I can’t get collar off end of hose to disassemble fitting. Please explain this process if fittings can be disassembled/reused
Actually, it is the other way around sort of.
Place the hose and big collar in a vice, enough pressure to grab the collar, take a 90-degree fitting off one of your fuel filters, screw it into the fitting and tighten,
Now take a wrench and place on nut above the large collar, if I remember correctly turn nut and 90-degree fitting counterclockwise it might be clock wise, cannot remember, anyhow unscrew the nut/fitting from hose and collar.
Once removed place hose in vice to hold hose about 1 inch away from collar, take wrench and turn clockwise /countercockwise and remove collar.
You have to use the 90-degree fitting to dissemble the hose as well as to assemble.
Now that said, I just cannot for the life of me Rember which way the different items turn to remove, I do Rember that the collar is opposite of the smaller nut and fitting.
Assemble new hose and if the collar seems loose them dissemble ,, place one turn rubber tape at end of hose on a 30 degree slant ,screw collar on hose, you may have to use a semi sharp object to push and to hold tape in place as you turn on the collar, bottom out the collar on the hose end, now place hose and collar back in vice and grab collar, take nut and assembled 90degree fitting and screw into hose and collar. do not bottom out on collar with nut , the nut must be able to just turn when screwing nut on to 90-degree fitting when fitting has been put back on filter.
Rember that you can use a ss wire at collar end as extra security after whole system hose has been assembled.
almost all of the fittings are -5 fittings except for one hose assembly, cannot remember which hose. Ther is one hose that is -4.
I would remove hoses and then measure each one from end of collar to end of collar and add 1-1/2 inch to each line as it will make it easer to reattach the hoses.
First hose takes about 30-45 min to do , all other hoses can be done in ` 15 min each hose.
I spent about $ 45 on hose total for I think 20'.
Spec hose is $12-18 dollar a foot.
If you replace the oil line, and I expect you may need to, I would get spec hose from an airplane supply company.
