The Triton V-10 does not have spark plug cables you basically have a high voltage coil for every spark plug, when you do the maintenace of the plugs you disconnect the wires on the "coil" and then you pop the coil and the "boot" hoppefully both will come out together, to replace the spark plug called a peanut (thin 5/8th socket) you are going to need a thin spark plug tool and an extention since the plugs are nestled in a hole, make shure that before you remove the boots you blast the area with air to remove any debry lying arround the area, then before you remove the spark plug give the hole another blast of air to remove what ever may have fallen while removing the boot, I do recomend to do one plug at a time, blast of air,pull coil, repace plug, when assembling spark plug use an aluminum based antizese not a copper one, then use a dielectric paste on the boot and the inside of the boot, reassemble and move to the next plug, when all are done connect the cables back, be carfull in torking the plugs some times there is a problem with some heads.
The fuel filter is on the left frame rail "inside" and has a plastic holder with a screw on top that holds the filter to the frame, the filter requiers a tool to pop the ends off, your parts supplier will have the tool, after you have the filter out with the mounting plastic, drain it and you might have a hard time geting the filter out of the mount, it is nearlly imposible to do it on the frame, make shure that you pay attention to the direction of flow, the filter has an arrow, for Gods sake have person with a fire extinguisher wile you do this.
I hoppe that you used distilled water when you serviced the cooling system, most tap water contains to many minerals and cause a lot of problems.
I hope it helps a little.
