GL1800 oil pressure switch

Post by wingman09r » Fri Nov 13, 2009 4:19 am

Good day folks.

I am looking to install an oil pressure gauge on my '08 GL1800. The sender goes in where
the low oil pressure switch now sits above the oil filter. Does anyone know what the thread
size on the engine case is?

I did the same thing on my '98 GL1500 and in the process found out that the engine case
is threaded for a 1/8-28BSPT, which is what was on the low oil pressure switch. This is
not a standard thread (in north america anyways) and I had to find a 1/8-28BSPT die to
"rethread" the sender to make it all fit.

Thanks much.
