Fuel line and rudder cable rubbing
Author Last Post
Thanks for the replies.  I am on try many to replace but i will give preferred a call and see if they have one. Thanks for the tip.

I had a similar problem but it was the left tank line near the aft
attachment to the fuel selector.  The center flap cable was rubbing on
it and made a grove. Some time prior to this happening the fuel selector
was removed for new seals, and the line was disturbed.  I made a temp.
repair with fiberglass cloth and epoxy, but subsequently bought a nos
line from Preferred Air Parts and replaced the damaged one.  The grove
was in a bad place as a leak would be impossible to shut off since it
was upstream of the selector.

The area under the floor is often not well inspected during annuals,
since a proper inspection requires removing the seats, carpet, and most
of the inspection panels, (sometimes need to put a light in one hole
while looking in another).

John,

Got the line out with a short craftsman 7/8 wrench.  Not really that bad at all, arm is cut up but better than burnt up.  On try three to bend new line correctly.  Patience is key and your right it was messed with, fuel flow part was installed aft of firewall.  Thanks for the reply.

   Jason,

   Best practice is to replace the line, sometimes in the inspection procedure for the fuel system there will be tolerance given for wear in the tube, but since there should be no cable contact in the first place, as designed, you get the picture. There may be something in AC43.13 on fuel lines and wear....Fuel lines get bent and messed with through out the years and it is rare that you see a line in an old plane that is as designed. That is a tough spot to get to, when I put a new line in my plane I had all the interior and peddles out...and the job still left mark on my arm for week not to mention trying to get a wrench in there and torque that B nut.

Gents,

The fuel line from the fuel selector to the gascolator has a groove from the rudder cable on the passenger side.  My question is how to fix.  Most likely we pull line and add a bend to increase the space but how in the world is this an issue since the last time that was out and/or inspected (last year).  My only thoughts are the rudder cables were adjusted last year and maybe it is less tight (looser) than before (in spec BTW).  At any rate it has to fixed, not exactly laying on the line (has a rubber coating on top) but you couldn't put a dime between them either.

anyone else experienced this, not ideal and i am not fond of fire inside an aircraft.

specifics-1955 180, camera hole mod...yes the gearbox has been out (windstorm and hit by another aircraft) but repaired properly many years ago.

Thanks guys, Jason
