My fuel system originaly came out of an 87 ranger with a 2.3. the 2.3, 2.9 have the same tanks/pumps in gen 1 rangers. Mine is a metal tank, its sending unit is the same as what was in it before the truck was conveted from a carbed 2.3 to a FI 2.3 to a FI 2.8. Basiclly my dad took out the original tank, hooked up the sending unit wires on the FI tank to the truck and it worked fine (other having to add a couple to run the pump in the tank). Just remeber that my truck has the 2 fuel pumps, the low and high pressure but due to going to Duraspark, I will be by passing the high pressure pump and just using the low pressure one. I will do a write-up with picks and all that stuff on how to convert to a Duraspark on my and my dads truck.
