Brass No-Crush Insert for 3/8" Nylon Tubing Compression Fittings
If you are replacing 3/8" nylon lines on your M35A2's fuel system or just chasing a nagging leak make sure that you will need new no-crush tubing inserts.
A leaking plastic fuel line on your multifuel 2-1/2 or 5 ton truck is no joke. It makes for a messy engine compartment - even a fire. You tighten the fuel line nut but the leak only gets worse. That's because the metal ferrules used with the tube coupling nuts can cut through the nylon line. The more the nut is tightened, the more the ferrule cuts into the tubing and the more the line leaks.
To fix this problem you must use no-crush tubing inserts when installing new lines. These inserts prevent the ferrule from cutting or crushing the tubing.
