dcskater602- I used a holly 190lph from a mustang gt. part number 12-901.
Was your mustang pump longer than the bronco pump? The pump I bought was, so giving the length I didn't see it fitting.

If Mustang pumps fit, Walboro makes a 255 that's only like 50 bucks.
The SVT Focus has one that's somewhere around 300lph. That's the most volume for that pump style that I've ever heard of.

300LPH, thats crazy. :) Even 255 is way more than we would ever need in a bronco. Interesting though. I noticed the pump I used has a one way valve built in where as the bronco it was built into the plastic housing. I assume this is to keep the fuel from draining back when the engine isn't running.

The Focus fuel pumps are the trick for the super/turbocharged mustang crowd.

Exactly. Otherwise it's not going to readily start. Eventually those valves stop working right, and you have that problem. The trick when that happens is to cycle the key on and off once or twice to let the pump prime a couple times before starting it.

Dude second paragraph

"My factory pump has been screaming like a cat caught in a blender for almost 2 years now. Not wanting to replace it with an over prices original I bought a WALBRO 255LPH fuel pump, part number GSS340 and the 400-812 install kit. This kit is made for a 5.0 mustang and is good for up to 500HP a little over kill for a stock engine which mine isn't."

Must need that flow rate for the higher RPMs.

Come to think of it, i bet thats why my remote starter would only work ever now and than. And I notices when i went to release the fuel pressure to do the fuel pump which was right after I drove it on the hoist, there was no pressure just a couple drips. The first think I noticed after I did the swap was the pump doesn't kick on when I first turn the key, I got in a habit of waiting for the pump to stop before I cranked the engine over.

yes it was the same length as the one you put in. However, when i cut the black plastic clip off the top of the pump it was able to fit it in as long as I took the smaller plastic screen cup off the bottom of the pump. Since the Bronco FDM uses the big bag-screen it didnt need it.

The only thing that looks different is the hard lines are longer comming from the top plate, other then that, the FDM (plastic cup thing) itself looks the same, unless I missed something. I dont mean to be an ass or anything, just trying to understand what is different.

I didn't think you were being an ass. Looked different to me in shape was all. Not having seen one in person I wasn't sure if the same mod would work on the bronco - this was before I found out you did it to yours. This is all good info, learning lots here.

cool, same here very quiet/
I was concern about removing the slosh can, though I might have problems in the corners or steep grades on low fuel, turned out to not be a problem.

I seriously doubt the Focus needs that flow rate, it's way overkill. But my thanks for Ford for producing it. You can support well over 500hp on one.

Yeah that's probably exactly why.
