I started a new thread for this since it is separate from the Andair fuel pump problem thread that led to this one. (See https://vansairforce.net/community/showthread.php?t=185143).
Due to the failure of my Andair pump, I elected to install an Airflow Performance pump in my -14A. This is a "one-off" installation because the aircraft is AOG and I need to get it into the air again ASAP. It is probably the first non-Andair pump to be used in this RV model. My arrangement is with the pump and filter mounted in line, which is longer than the Andair but still fits into the tunnel. It is not as elegant or compact as one which will likely be forthcoming from Airflow Performance and Aircraft Specialty/TS Flightlines. FYI, I received the pump on Monday afternoon and flew the airplane for the first time with the new pump early Thursday morning. Ops normal.
I finally (sort of) figured out how to use Smugmug as a photo host for VAF posts so have saved the process for doing this install at the link below.

Again, this is a one-off install I came up with that works fine for my -14A. Feel free to copy and/or improve on it as you see fit, especially if you have an AOG situation and need to get something else to work before a new package becomes available. The hardest part was working with my head against the right side rudder pedals trying to form/fit the fuel line from pump output to firewall fitting. With a tunnel mockup or an aircraft under construction, this would be much easier. Doing it on a flying aircraft is more difficult but still I had it flying again in a couple of days.
The AFP pump when dead headed put out 32 psi and when the fuel line was opened, flowed 43 GPH into a bucket, so it is plenty of pump for the IO-390. It appears to draw a couple of amps more than did the Andair.
Ground tests showed no leaks and flight test over the airport today was totally normal in all respects.
