If you want you can take the sending unit up to the cab, and hook it to the gauge and move the arm, to see if it works properly. If you are missing parts and still unsure of it, you can buy the entire kit with gasket, locking ring, and filter for $40 from a number of places. I just dropped my tank and replaced the sending unit, all the fuel and vent lines and new wiring. I ran a new home run to the gauge and ran the ground wire out and anchored it to ground with a lug. I also cleaned and painted my tank with spray on bed liner.
I don't know what brand it is. I googled the number on it and got nothing. The number is: Y2lC-SP18
Also, the fuel sock/filter in the link above is for the 20 gallon tank. Would that also work for my 15 gallon tank, or do I need to find a different part? I am having a hard time finding one.
I actually don't have the old one or the tank at my house right now, so I cannot compare the two. I am working on it at a buddy's place. I was just rummaging through the box of parts that the OP gave me and remembered he'd mentioned that he had a new sending unit.
This fuel sock is wearing me out. I can't find one that is for a 15 gallon tank.
I have a 4.0 w. F.I. so I run an in line electric pump. Would it be okay to use an inline filter after the sending unit but before the pump and not have a fuel sock on the pick up tube? If that'd work, what would be the best way to lengthen the pick up tube?
Ive heard of people putting a length of fuel line on the end and securing with a hose clamp, but I would worry about that picking up gunk that builds up in the bottom of the tank and possibly getting clogged. I know you want to save that sending unit, but it is a pain int the a@# to drop that tank. I tend to try and save and salvage some parts, but those that can strand me out on the road or trail or damage more expensive parts (Fuel pumps / injectors) I have learned over the years to belly up and get the correct parts. Im not a a quadratec salesman, but as I mentioned earlier, I just purchased the entire unit for $40, it had everything you need to put your tank back the way it is supposed to be.
