    Default Fuel line and injector caps

    I am about to install new cylinder heads on my 95 c1500 6.5l. Never did it on a diesel before. Everyone keeps telling me to make sure I don't get any dirt in my fuel lines and injectors. What would you guys recommend for me to use to cap off my injectors and fuel line to the IP?

    Put the injector lines somewhere clean where dust is not blowing around. Wrap masking tape around the top of the injector so you have a protruding tube and squeeze it shut. That is all I have done a number of times. Weld up a handle from thin steel tube to bolt onto where the rocker shaft was, the heads are heavy and in a difficult position to lift out and back in.

    I was thinking that with the masking tape. That was one of my options. Now the only thing I am worried about is breaking any of the manifold bolts. My truck has always been in Florida since new so hopefully They will come out fairly easily. Fingers crossed. Thanks.

    The crossover pipe nuts were the stuck ones on mine and I had to set fire to things with the oxy/acetylene to get them loose, but if you replace one head then the other, the manifold can stay connected to the cross over pipe. I had to run a die down the the manifold bolts, the thread was half full of something harder than steel.
