This inexpensive kit will allow you to replace the old, hardened, and brittle fuel hose in your 601, 602, or 603 diesel's engine compartment, as well as those old, worn-out factory clamps, with new, high-quality, German style clamps that will not cut into the rubber hose.

Product Details
This kit includes 4 feel of high quality fuel hose and 8 HD clamps. The hose is not biodiesel spec but does hold up well to biodiesel if used in small amounts. If you are running B80 to B100 we recommend our other Super Flex fuel hose specifically made for biodiesel. (Just typw super fuel into the search box.)
PLEASE NOTE: No instructions are included, but replacement is very straightforward.

We also recommend replacing the hand primer pump unless you have done that recently. If you want faster and smoother cold starts, easier bleeding, and more power under load, consider installing an electric fuel boost pump inline between the fuel tank and the injection pump on your old diesel. It takes the strain off the mechanical lift pump, which is always trying to suck fuel up to the engine from the tank. Other diesel manufacturers have done this!
