Yes, I did. I'll definitely ask for help if I need it.

KPM800 arrived on Saturday and I installed it yesterday. Install was not difficult at all. Took my car for a spirited drive and had no hiccups when revving it to 7,500 RPM on multiple occasions. The real test will be Aug 15th for my next track day.

Im running the KPM 1000 and love it where did you mount your fuel filter

There is a small hole on the fender just under the strut tower brace. I used one of the bolts to mount it there, but I will likely end up drilling 2 holes in the K member or strut tower brace to attach it there.

I sliced off the unused sound tube tab on the shock tower and made a simple bracket to mount the large Radium Filter. There's even a weld-nut and hole perfectly placed on the shock tower to aid installation. Access to the dip stick is maintained and the filter tucks under the cowl/strut brace. I don't like the idea of mounting the filter in a hot engine compartment but it's so practical compared to an underbody project plus my hood is vented and I feel a little more comfortable with the Russell braided fuel lines over the OEM style plastic plumbing.

That looks good. The mounting hole on my 2021 is horizontal. I don't think I have a vertical hole, but I'll look when I get home. Did you reinstall the K brace and strut tower brace?

Supplying enough fuel for a drag car or occasional street blasts is completely different from top speed runs and track days, especially with long sweepers. Keeping the bucket “full” is basically optional for street and drag use.

Generally you want to keep the bucket full all the time in all driving conditions. This helps keep the fuel pump cool and insures you don’t starve the system of fuel.

When you install the new pumps make sure you get any air out of the tube that crosses over from one side of the tank to the other. If air gets trapped in there it acts like a toilet trap and slows down fuel transfer across the tank

Ideally yes and I completely agree, but next to no one with a modded Mustang can claim theirs does that.

Under hard cornering or with less than about 1/3 tank of gas, the bucket is only filling from one saddle. I’ve tested the fill rates and can tell you that only a stock gen3 on gasoline is capable of keeping the bucket full from one side at max power. A stock gen2 or gt350 won’t. Convert any of them to e85 or add a supercharger and the consumption rate is faster than the single-sided fill rate. I tested these bucket fill rates myself.

The grace is the bucket “capacitance” gives you some time at wot before the pump is starved, and *usually* that gets you well past a quarter mile and 140+ mph.

How, I reconnected the crossover into the KPM adapter fitting without thinking about it.

Both braces are going back on after other mods are finished.
