O-320H2AD Fuel Pump

[WingnutWick]

Hello all - needing to replace the fuel pump on an H2AD. Looking at one of the old O-320 H series parts catalog it shows the fuel pump as LW15399. Looks like the only available LW15399 on Spruce is the: Tempest Overhauled: LW15399 LOW PRESSURE 4 - 6 PSI LONG ACTUATING ARM PART#08-15399 on spruce and that's backordered. My question is - is there another part number for this, or is this a pretty specific pump that is not replaceable with say the AF15472 LOW PRESSURE 4 - 6 PSI CHANNEL ARM FUEL PUMP?

Also looking at the Tempest application chart it references 41270 - is this also an acceptable replacement?

Thanks!

I just replaced the pump on O-320E2D and comparing notes with a buddy who is replacing the pump on O-320 H Series, the H requires the Long Arm pump and cannot be replaced with the AF15472 short channel arm. I think your second option (instead of LW15399) on Spruce is 41270 overhauled and there is no stock showing, because it is ordered in. If you order it then the core charge of $100 will be added and refunded when you return the old pump afterwards.

Just for comparison, I bought the new Tempest pump for mine with channel arm; the old laminated arm is only available as a an overhauled exchange and new ($415) was less expensive than overhauled. Unfortunately the overhauled long arm for the H series is $644.00.

My go to is Airparts, mostly because they are an 8 mile drive up by KICT and they can get just about any aircraft parts.

I have a LW15399 long arm 4-6 psi. We pulled this off our 2AHD to upgrade to FI. If you still need one.
