If you have a Magneto, you should drive your tach off that. I don't see where the Oil pump has anything to do with it. My EFIS ( Dynon ) just needs to see the pulse that is driving the ignition. If I have my VW ( which is for sale ) on the plane, then I would have the P-Lead running to the Dynon input. On my Corvair installation, I have the line that powers the coils running to the Dynon inuts.
Are you using the engine pump? If not, Great Plains and Revmaster use a cover that works. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2012 - KR Gathering in Mt. Vernon, Il MVN 40th Anniversary There is a time for building and it is over. Daniel R.

Or of some way to buy a cap that will thread over the drive & seal it off (To prevent gunk getting in, or oil getting out)?
