Re: 1995 DT466 Fuel line
The "quick fix" would be to cut those rubber hoses in half, and use whatever tools are necessary to remove the old hose and yellow ends from the metal tubes. Then put new sections of hose in place and clamp with hose clamps. If the problem is air coming in from those rubber hoses, then that fix would get you back on the road and likely would last for quite a while, if not indefinitely. You will of course have to re-prime the fuel system once you open it up, or it will take a whole lot of cranking to get it started again. Be sure to buy good quality, diesel-rated tubing. Also, not all hose clamps are created equal - get the kind that is designed for fuel hose if you can, as they are designed to stay round as they clamp down. You might also have to cut the metal tubing if there is some kind of irregularity where it was previously crimped that would prevent the new tubing from sliding on properly.
