I paid them to replace the pickup tube, and it could be done without pulling the engine (on the 751, anyhow). I couldn't even see the pickup tube fitting on the top of the tank. I think they had to open up the cab, and lay down on the hydraulic lines and somehow reach back through near the inner side of the engine. Obviously, they knew what they were doing and I didn't, so I paid a couple hundred bucks to have them do it. My only other idea would be a wacko idea. If you're looking at pulling the engine to fix this anyhow, why not try waiting until the tank is about half empty, then poking an air hose into the tank and bubbling the diesel around for 10 minutes or so. Maybe some of the crud will jiggle loose from the filter. Then, use an external pump (I used a Holly Red gas pump) with a long hose poked into the tank thru your diesel filler neck and pump out all the bad junk you can. Maybe even put in a gallon or so after it's dry and do it again. I know this is a lot of fussing around, but it might save you pulling your engine. --- Bob</p></blockquote><p></p>
