Do you think this will work?
 

This is what I'm planing on using to tap for the oil feed line.

first fitting on the left is the metric to inches fitting from the Autozone Sunpro Kit, then an npt extension, not even an inch long, and the T from the Sunpro kit. Then the top outlet on the t I'll use an npt to -4an fitting for the line and on the far side the oil pressure switch.
Thanks

yup, looks good, even though they are tapered fittings, it doesnt hurt to throw some thread sealant or tape on them.. But thats just me. ;)
