I seem to recall a special Lycoming P/N fuel line fitting #6 all steel

that threads into the carb with a jam nut with a "O" ring to seal. You

have a normal aluminum fitting threaded into the carb. I would go with

the steel fitting.


	


Let's talk about this.  I am using a steel 90 degree fitting with O ring and 

jam nut on my carb.........but.............my new ECI cyls have alum 

fittings for the oil return lines, Van's supplies alum fittings for say, the 

MP nipple, 45 degree carb fitting, etc.  Nowhere on the jugs or supplied by 

Van's is any steel fittings.  I have seen numerous airplanes with alum 

fitting, say on the prop gov and case nipple for the stainless oil line. I 

have steel but OK, for discussion, what gives.

Hi Dana, Reread the previous  post...the fitting described here with the O-ring and jam nut enables you to  clock the fitting in the direction you choose....then tighten the jam nut  against the O-ring to seal it tight. The fitting happens to be steel but it  doesn't have anything to do with the steel vs. aluminum topic. The  fitting can also come with a port for the fuel pressure line....I  think you may have one of these on the upstream end of the hose......don't have  pic in front of me???

  

 Back to work buddy  :^)!!

Hey Rick what are you doing not working on the 10:-)



Yes, I have both the fitting you talk about however, I have heard from so 

many people saying you ONLY want to use steel fittings on anything on the 

engine.  Now is just a good time, with the alum fitting I was using to 

orient the hose, to discuss what is the deal with using only steel fittings 

when ECI and Van's both supply us with alum fitting either on the cyls. or 

with the firewall forward kit.



PS, I have some alum fittings and some steel.

Dana,



I would not mate aluminum to aluminum because of the

galling that will take place.  You will get the

fitting in but you may not get it out as the fitting

galls.

Originally I heard that it was due to aluminum melting prior to steel in 

a fire.  OK, that's reasonable if you plan on an engine compartment 

fire.  However, I doubt the integrity of the fittings will make a whole 

lot of difference in the eventual outcome.    Then someone said that 

steel fittings were more resistant to fatigue cracking.  OK, that sounds 

reasonable.  Balance the prop.

FWIW, I have aluminum fittings in the engine compartment of my Pitts 

..... because I had them and it was before I knew about the 'concern'. 

 They've been faithful for 25 years now.   Hmmm.  Maybe I should 

worry???  Wonder what the warranty period is.

The only fitting that has to be steel is the prop governor line 

connection at the front of the case, for those Lycomings with rear 

mounted governors. Those were aluminum originally and had a history of 

cracking. That is required by AD. The rest generally are aluminum.

OK, that is good enough for me.  I took the "do not thing" off my signature 

line.  Great work guys.
