<VV> re: Oil pressure sender

[airvair]

I'd like to add that some senders need a solid electrical ground to make 
them work. To do that with an adaptabolt, you need to use a copper 
washer in place of the bolt gasket. The trick here is that in order to 
seal, all surfaces need to be perfectly flat. If you run a mill file 
over the Corvair's oil filter adapter housing, where the bolt gasket 
seals, you'll usually find that it is anything but flat. Just file it 
off flat with the mill file.

I think ALL Corvairs could benefit from having this surface filed flat.
