Just thought I'd pass this one along. Wandering the local AutoZone this afternoon I ran across the followingfor a grand total of $5.40:

Sunpro Metric Adapter Kit Pn CP7573

"Includes 5 brass busings for adapting electrical and mechanical gauges/senders (except mechanical temperature gauges) to Metric thread engines."

M10 X 1.0 to 1/8 NPT
M12 X 1.0 to 1/8 NPT
M14 X 1.5 to 1/8 NPT
M16 X 1.5 to 1/8 NPT
1/8-28 BSP to 1/8 NPT
