Electric fuel pump STC reference paper work

Need more info - which engine, fuel tanks, etc? Do you have the OKC FAA disc for your aircraft? Lots of support/info here but always give more details - the pump may be a part of another STC. I have 0-200 with electric and mechanical pumps with 30 gal tank system - electric pump was part of bigger tanks. Matt can probably help you but I think he may need more info. FWIW

I just purchased a 1946 model 415-C, it has the electric fuel pump but there is no paperwork on the logs. I am looking to see if anyone has  the reference to the STC paper work so I can verify the prior installation before submitting 337 form.
