The picture looked like hyd hose with reusable fittings .It take a special hose when using reusable fittings .The hose might be good for both hyd oil and fuel . I'm not sure . Most of the hoses we repaired were for hyd oil .We sold the hose loose also that way you could repair in the field and not have to have a crimper or swedge .

You are cool RT....no criticism taken...

You know me...I think well outside and hopefully usually well above the box....

Yes tape could be an issue and I didn't use any downstream of the engine mounted fuel filter. It's what I had handy the day I was putting all this together and my son had stolen back the great thread sealer he had given me and I forgot.

But if careful where the tape is on the threads...and there is still a filter downstream of the tape used...I don't see a big deal and now after 2500 miles...I may change my prototype out anyway.

Good catch though...but despite a few who don't think so...I think long and hard about even the little issues before I press on or stray from the "recommended".

TeflonŽ tape (polytetrafluoroethylene or PTFE tape) is used in sealing pipe threads. It is wrapped around the exposed threads of a pipe before it is screwed into place and acts a little like putty under compression to make a seal.
TeflonŽ tape is only effective on tapered threads and should NOT be used on straight threads.

Do use on tapered threads Don’t use on straight threads

TeflonŽ tape should NOT be used on CGA fittings of compressed gas cylinders, because these fittings have straight threads (a CGA fitting connects a compressed gas cylinder to a regulator or transfer line). Mis-application of TeflonŽ tape on a CGA fitting may be hazardous. It can prevent an appropriate seal and cause gas leaks and pieces of tape can easily break off and form a foreign body contaminant that could jam a valve seat, causing valve failure.

60 gph... Same as the filter.

Fuel rated hose or hydraulic hose is fine for diesel and if protected from chafe tends to last longer (but doesn't look as purty) as copper etc. It does, however increase your vulnerability in case of engine room fire. Most commercial small ship survey regulations require an automatic, fire activated, self closing valve upstream of any non metallic fuel reticulation. It's actually pretty easy to achieve. Find a suitable sized spring loaded to close valve and tie open the valve handle with a piece of suitable sized flammable cord. Fuel line catches fire, cord burns, valve closes, hopefully minimal damage from a fuel fed fire.
