Here is the start to my fuel pump build. I have a 80 cj5 with stock steel tank. I bought the stock sender off Amazon for under 30 bucks.
The stock unit has a bent tube that needs to be cut off. I measured the length of the tube and it's about 8 inches. I simply laid out the fuel pump with attached hose and marked the tube. I live in a remote area of Alaska and so I'm waiting on a tube cutter and flairing kit to arrive. Before I cut anything though I'm going to measure the previous fuel sender and make the cut match.
I also ordered a new Dephi EF0114 fuel pump, it exceeds the psi requirements of the 5.3 vortec and is a commonly found pump in GM cars/trucks. The cost of Amazon is about 65 bucks.
I also bought an assorted pack of heatshrink, a 175 piece solderless terminal set ( I am going to solder everything) and I bought a box of nylon and fiber washers.
The electrical connector for the fuel pump is AC Delco part # PT2352, gm # 88862271, also ordered from Amazon.
The problem I had with my NOVAK pump is the fiber washers desintigrated and the screw started touching the sender and shorting out, also the wire connector in my opinion was poorly constructed. The ground wire kept sleeping off the blade on the sender and the shrink tubing was bunching up exposing the power wire which began rubbing against the inside of the tank.
I soldered the wire into the blade clamp, made sure it was a very tight fit on the sender blade, and double heat shrunk the connector.
Next I had to make a hole in the sender for the power supply. I think I used a 17/64 bit. I chose the spot I drilled through simply based on space available and I noticed small spot welds that I wanted to avoid.
I looked all over for nylong shoulder washers and found these, I'm not an expert on sizing so you can tell the inside hole is way toooooo small for my 3/16 bolt, so I pull out my drill and used a 3/16 bit to drill the hole bigger. I lucked out and found this scrap piece of still which held my small washer in place while I drilled. I made about a half dozen of these so I'd have spares.
These nylon washers are Off-White Shoulder Washer Shoulder Lenght 0.046, shoulder dia. .518 Thk .031 OD .305 ID .080. I ordered these off Amazon too.
The washer turned out to have a wee bit of an interference fit and kinda snapped into my drilled hole which was perfect.
In the pics I'm using a 3/16 screw when I fly to town in a week I'll buy a 3/16 bolt and lock nut. I also have a box of fiber washers which just came in the fiber washers will also be used. I plan on actually doing a write up of this pump build but hope this would help you with yours. The total cost was under a hundred bucks and that included buying a soldering iron and a few other tools.
