My 912 engine kit  came with a brass "Barb-Tite" fitting (hose barb). From what I've read these  fitting require no hose clamp and just need the hose pushed up over the barbs.  Supposedly good to 250 PSI.

  

 Will these work with  fuel injection hose or will they only work with specially designed  hoses?    Is it really safe to have a fuel line without a  hose clamp?

  

 Thanks,

This is the first time I've  heard of this.  All my barb fittings have clamps over  them

 I use them extensively, but only as designed. There is an entire Aeroquip series that is clamp-less. Aeroquip is reputable and I'm ASSUMING their design is proven, though I didn't prove it myself. I used this system previously on a Porsche remote oil cooler and in 12 years never had a fitting failure, though I once had a mid-hose failure. Of course I replaced the line every few years. 



 On all other "barbs" I use clamps. (E.g. fuel pump, carburetors.)

Guy,

  

 What  about using the "Barb-Tite" fitting with typical fuel injection hose?   Since everyone recommended the fuel injection hose over the old H6000, I changed  all the hoses to fuel injection hose. But now I wonder if I can use it with the  barb-tite fitting.  Would it hold?

  

 Thanks  for the help,

 Don't know. I used the Aeroquip "Socketless" system for the fuel lines from the wing tanks to the fuselage, about 1' on each side. The rest of the fuselage fuel lines are aluminum. The "Socketless" system requires no clamps and is rated to 250 psi working. I can't imagine any unpressurized line coming off a "Barb-tite" fitting, but I don't have any even anecdotal data. Why not use clamps? I use them on all my fuel hoses in the engine compartment.

Yes, they'll hold.  Just buy some of the hose  and fittings.  Install a fitting in a vise then install the hose.  Try  to pull it off.    Clamps are optional.

No info on "barb-Tite". The off road race trucks are now using Parker "Push-Loc". One heats the hose with hot water and push it on the fittimgs. Good for 250psi, once installed. Use on high pressurte fuel EFI fuel systems. Fittings are availble from multiple sources Like Parker, Earls, etc. Fittings are available for flared AN or pipe threads. The hose is special not the standard SAE stuff

They are real easy to install and no clamps are used.
