Hello,
I was wondering if anyone konws where the Orifice tube is located on a 1998 Ford Ranger 4.0 with factory A/C. Thank you advance.

It should be right where the line splits where it goes into the evaporator.

 

I beleive the evaporator is also known as the accumulator, correct? I have the accumulator removed because it has a pin hole in it. I do not see a "split" in the line. The A/C line goes into a large black box right behind the accumlator.

Accumulator is not the same as the evaporator. Accumulator is tank looking device underhood near firewall on passenger side. Evaporator is finned unit inside heater and A/C housing. Orfice tube is inside evaporator inlet pipe where high pressure line (bottom pipe) from condenser (in front of radiator) attaches.
