I am istalling it on a 48 Studebaker with positive ground. A word of caution. read somewhere if it installed in reverse polarity, the pump will run, but not output anything. And if your Ford is six volts, as my Stude, get a six volt pump. don't mess with voltage changes. Tipsfrom other owners tell me it will flow thru if turned off and only the old pump reunning. Guess its real purpose is to overcome vapor lock.Remember those ?

I have an 09 f150 with the 5.4. I've got the Edge CTS, a K&N CAI, throttle body spacer, and custom exhaust. If I drive with a light foot I see anywhere from 15-17 city and I've gotten 23 hwy with it set to "economy." On the hwy though, anything above about 70 MPH and you won't see that good. I did tow a 4 place Seadoo trailer from CA to Utah and was getting 19 mpg using the "towing" program. The programmer is compatible with the K&N intake. When you run the setup you can select between a couple different CAI's and it will configure the tune for it. Overall I'm pretty happy with it and seen 3-4 mpg increase on both city and hwy. Hope that helps.

Yes I'm showing that to be the correct fuel pump for your engine. Let me know if there's anything else.Thanks, Kelly

I don't have any problems using the octane booster, no spark problems or exhaust dust. I'm tuned for 95 octane and I just use 91 with the booster. But I do use the whole can per fill up, if that makes a difference.

Sammy ... I bought a new fuel pump for my Yamaha golf cart and it seemed to do well, but now, I have the same problem you are having. It will move when you push the pedal down, but after a short while will just stall and sit there ... no matter how much you push down the pedal. We then have to push or tow it to where we're going. I have been told that it is probably a carburetor problem, but I haven't had anyone look at it yet.

I had the same issue, check your fuel pump. My fuel pump housing had a crack in it and was only pushing half the fuel to the motor that was needed. I replaced the pump and it fixed the backfiring.

If the problem is related to the poppet injectors, yes. I changed my injectors for a different reason but I ran marvel mystery oil mix in gas about every third tank.

I am running mine on my 2006 ford escape EFI. I have a 20% increase in fuel economy, but it froze this winter. Your better off with a Wet Cell in your cab and running the water solution levels low to avoid damaging the cell. I will be running mine in the cargo area with two plastic ketchup 7 lb containers to hold water solution and one 3 plate cell.

I have an 08 Pro-4X sb crew cab. My truck definitely performs better than stock but i loaded the performance tune that requires 91 octane gas. I have not tried the other available tunes. Overall pleased, no downside. My truck only gets driven 3-4k moles per year so the premium fuel doesnt hurt too bad.

Probably not. I have a friend with an F-150 of similar vintage, and he tells me the engines are different, despite having the same displacement. In the absence of other resources, I'd probably just call up a Ford dealership, and ask them if the part number is correct for your truck.

I have now problems with fuel overflowing out the filler neck. Make sure the overflow valves is mounted straight up and down as stated in the directions.

It could be the fuel filter. The manual suggests you change it yearly or after 50 hours of use. I had this issue and that is what it was.

I cannot speak for your engine, however with my 5.3, even with the program now removed. I still have to run 93 octane to keep the truck from skipping. Didn't do that before the programmer. Get a custom tune. You'llBe much happier

I found cleaning the pump intake solved the problem. When I took my out, it had cat hair plugging the intake side. Once I got it cleaned out, it works like new!
