Hi Everyone, I'm brand new to the forum and pretty new to trucks in general as well. Earlier this year I became the owner of a 1993 F-350 Ambulance with the 7.3 IDI, that has already been converted into a camper. Truck is great with basically no rust (from the desert) and low miles, but it's slooowww. I did some research and decided to go ahead and install a turbo kit, I went with a new Hypermax kit because of the cost and parts/service availability. I'm currently working on the install and have never done something so mechanically involved before so it's a huge learning curve.
One part of the install has me particularly stuck/confused at the moment though. In the instructions Hypermax included there is a section that reads as follows : "If equipped with a fuel return hose facing rearward out of the top fitting of injection pump, remove this hose. Turn fitting 180 degree while holding hex adaptor with wrench. NOTE: Use extreme caution when turning fitting. Turning hex adaptor in aluminum pump hosing will result in thread damage. Remove steel fuel return line and cut bend off. Deburr, clean and reinstall fuel line. Connect new hose and hose clamp supplied". Now turning the fitting 180 degrees was no problem, but that part that says "remove steel fuel return line and cut bend off" - I thought all the return lines were rubber hoses? There are steel, high pressure lines and one of them does connect from the back of the IP to the fuel/water separator, but is that a return line and is it what they are referring to here? I really don't want to start cutting high pressure lines without knowing for sure I'm supposed to. Also the kit doesn't seem to come with a new hose and clamp for this as stated. And if I'm replacing a steel line with a hose, isn't that asking for trouble? If anyone has done this install please let me know how you completed this step! Thanks!
