it looks identical to the stock pump , the only differences are it will not accept the factory electric plug , nor will it accept the banjo bolts which is fine .
its 3/8 npt , get a -6 male to 3/8 npt male straight fitting and a 90* that is 3/8 npt both ends , and a 3/8 compression to a 3/8 npt to screw onto that 90 . cut the banjo fitting off the end of the line that connects to the stock fuel line back to the tank and put the 3/8 compression on it so you can connect back to that line . take the line that goes between the lift pump and the fuel filter and deposit it in the circular hopper , get a weber 12mm to -6 male and 2 aeroquip -6 socketless straight hose ends , about 12 inch of aeroquip socketless fuel line to go between the pump and the filter , cut off the factory connector to the stock lift pump , and connect the wires to the new pump . no regulator is needed , summit sells all the parts you will need for a decent price.
you really should mount that pump back at the front of the fuel tank though . i will be putting it on my truck tonite in the stock location as a test , but it will ultimately be back at the tank with the stock line and lift pump left in for a backup incase this one dies , i hate being at the mercy of someone else .
