This is a new very high quality and US Made fuel hose for the M38A1. This is the short rubber hose that jumps over from the metal hose on the frame and into the fitting on the fuel pump. These are 7 1/4″ long just like the originals. These are always missing and many forget to put them on. You need something flexible to keep the vibration to a minimum. These have one fixed and and one movable end. The Fixed female one is 1/2″ x 20 pipe and the movable one is 1/2 x 20. This was copied from a NOS original we have as a sample. These are also identical to the ones we sell with the full steel line kits. These are made with US made hose and Weatherhead fittings.
