Fuel Pump for ATI
Hello,
I've just about finished my ATI install, all I have left is
mounting the fuel pump, wiring it in, and connecting the
FMU. I don't have the time to do all at once and was
wondering if I can mount the pump and plumb it in
without wiring it into the relay. In other words, will the
stock pump push fule through a non-running booster
pump with no ill affects? Obviously, I won't be putting
the belt on the blower until everything is completely done.
Also, if the boost-a-pump is wired in and running will
the engine still run ok without the blower belt or FMU tied in?
Oh, I heard mention that the directions in the ATI install
manual are wrong regarding the colors of the fuel pump
relay wires? Is this correct? I have the 5.4 -- which are
the correct wires (colors)?
Thanks much,
Bob

Im not sure if the pump will restrict flow or not. But you shouldnt have a problem running the pump if the blower belt is off. the FMU resticts return fuel line based on boost and increases rail pressure to force more fuel through the stock #19 inj. With out the blower there wont be any boost so fuel pressure should stay in the stock range.

You will have to wire up the pump to work. It will not impead performance while the blower is off. If you do not wire the pump it will severly hamper flow. The problem people are having is with the power wire. Run the fused wire to the pump. Run the yellow wire to the power terminal on the fuse block. Green goes to the fuel pump relay

With my ATI I am going with a Bosch in-tank pump. Naturally I will want to install a larger gauge wire from the relay to the pump but does anybody know if the stock relay will stamd the gaff. Does the Lightning use a different (heavier duty) relay?

Crash,
Your message regarding the green wire with the yellow tracer, I assume this is used to actuate the additional relay that comes with the ATI kit.
In my case, I will be running the replacement, in-tank pump only. My question was whether the stock relay is capable of carrying the additional amperage of the larger pump in place of the stock pump.
In the final analysis, this comes down to whether or not relay "301" is the same on a standard truck as opposed to a lightning which has the larger pump.
I'll check with my parts guy at Ford and possibly on the "L" forum.
