Looking for information on the fuel injected R-1340 used on the P-26B/C?

[ThomasP]

The P-26B (all 2 of them?) were fitted with a fuel injected model of the R-1340 - with the -33 suffix if my information is correct. The B models were flown a fair amount for evaluation. The P-26C was subsequently built with a regular carburetor controlled R-1340, but at some point the surviving C models were refitted with the fuel injected engine used on the P-26B, and apparently served out the rest of there time on this planet with the fuel injected engines.

What I am looking for is information on the engine and what the evaluation of the engine was at the time. Did it perform reliably, was it a maintenance problem, was it too expensive, etc? Any information related to this would be welcome.

I'm attaching some letters obtained by the Aircraft Engine Historical Society from the NARA Power Plant Lab Memo Reports dealing with this subject. There are a number of additional memos, but they deal with conferences on technical details like control linkages and redesign of the accessory case to accommodate the fuel injector. Hope this helps.
