I'm with RD - I couldn't be Rsed with all that. And when mine used to wet sump it was so bad that it blew everywhere if you just started it. I wouldn't use one of those sprung things though, it would have to be a proper tap.

I thought about fitting a sprung ball bearing valve but couldn't reconcile the risk of a stuck valve to the engine. I have fitted the kingpin awsv. Works really well, the switch is very well made and it has a reasonable amount of friction when you turn it. If it is mounted so that it is open when turned downwards it us unlikely to move when the engine is running.  I have used 'test meter' (ultra flexible and strong) wire with crimped and soldered connections for the switch connections. I also clip on a 'remove before flight' tag when its in the off position. Also check return oil flow is good whenever I start it. A lot easier than undoing the sump plug and draining. I guess you choose the solution that you feel most confident with.

Hi Dan,
Is the other side of the T in the feed line going somewhere or blanked off?

Hi John, other end is blanked off. Its simply used as additional support for the weight of the switch and attached oil pipes etc, so strain on the tank outlet joint is minimised.
