I am getting ready to convert my older 351W from a carb to a stock EFI system from a newer F150.

I have most of the pulleys and accessories what not from an '89.

I was planning to grab the upper & lower intake and as many parts from the same truck.

I want to grab a harness and computer. However, I want to grab the harness from one of the newer years that only has one fuel pump.

Any one remember what year went from a low pressure in tank lift pump with a high pressure pump on the frame rail to just the one high pressure pump in the tank?

 

I believe it was 90. My 89 5.8 has the 2 pump system, but i want to say my 90 5.0 did not. BUT its been 10 years since ive had that truck, so im not 100% sure

 

That is good.. there are more 87-91 trucks in the junk yard then 92 and up.

I just have to get all the emissions related parts with the conversions..

 

Yeah, it was 1990.
