Tips on removing / installing fuel line from tank
Do any of you have tips on removing and installing the flexible fuel line between the tank and the metal line at the wing root. I found it very difficult to access the line to attach it. Any tips would be appreciated. Thanks!
Make sure you clean both the tank fitting with the hose barb and the fuel line with the beaded end really well.
Lubricate both the fitting and the line and the inside of the new piece of Mil 6000 hose with DC4 silicone lubricant. Then slide the hose over the line so that you can match up the ends then slide it back onto the tank fitting. Yes, close quarters. You might tsry taking the top of the wing to fuselage fairing off and get a helper with a wooden dowel or something to work from above to halp push the hose one way or the other. Put clamps on in advance loosly.
Sorry for the delay in getting back with you. I appreciate your help.
I installed and removed the fuel tank several times in pursuit of resolving the leak.
I found an open end crowfoot on a long extension became a valuable tool to push the rubber tube on and off. I lubricated the nipple and the inside of the tube with Marvel Mystery Oil. As you suggested I installed tubing clamps loosely during the tubing installation. No doubt about it was a pain in the X#!X#!
I found the tank had two very small hairline cracks in it. One of the cracks was repaired many years ago with fuel tank putty. Both cracks were repaired and the tank reinstalled. No leaks and it is better than new!
