i hate my truck lately

That sounds right for a returnless FFV.

What the heck is a returnless FFV???? I'm pretty good with acronyms too and that has me in a loop.

FFV=Feed Forward Voltage
Little info.
Feedback variable FV is added to open loop or feed forward voltage signal FFV from block 226 to generate fuel pump voltage FPVOLT in summer 230. In this particular example, feed forward voltage FFV is generated in block 226 as a function of desired delta fuel pressure DΔFP and fluid flow through pump 72 (PUMPFF). When added with feedback variable FV, the resulting voltage (FPVOLT) applied to pump 72 will drive error signal "e" towards zero for maintaining minimum desired delta pressure DΔFP subject to the above described constraints.

LOL.

I was talking about the Flex Fuel Vehicle (FFV) 3.0 engine. The returnless fuel systems used in later Rangers operate around 60psi, except the Flex Fuel systems that are about 10 psi lower. That difference is why I had to swap my fuel pump during the V8 conversion, and repin the pump wiring accordingly.

Ha. still relevant. I will settle with a tie good sir.

If my employer didn't do random drug screenings, I would definitely want to smoke what you're smoking. That sounds like pure alien gibberish to me. But if you understand it, that's good. I want vehicles where I can connect the red wire to + and the black wire to - and the pump runs.

You couldn't afford what I smoke.

That's what I was thinking. The more I read it the more confusing it got. I need this broke down in redneck terms lol.
