allright so yes the v6 and v8 injectors are similar, bosch 4 hole injectors
Your truck is a ranger uses returnless fuel 65psi
The donor is a 2000 Explorer uses returnless fuel, 65 psi
You need 30 pound injectors for the 65 psi returnless system, bosch 4 hole
The wiring connectors are not that important, if you are doing a v8 conversion you can solder on 8 injector clips.
Forget trying to use a 24# injector designed for a 35 psi system in a 65 psi system to make them flow more..... you just need 30# injectors for the returnless 65psi system. I am SURE they sell these on Ebay. Your tuner should understand this.
I run a Walbro 255 lph pump in my 88 Bronco II sending unit, my BII still uses return fuel but next year I plan to convert her to returnless........
cooler fuel at the rail = more HP and better mpg, also less plumbing
