hi i been looking for a fitting to go from my block to conntect a oil line so i can run it to my sending unit. if theres a kit some where can someone post a link? i have a gsr b18c1 with a auto meter oil pressure gauge/sending unit.

 

does the fitting look like 1/8 pipe thread? it's probably 1/8 BSP Honda uses that a lot if it's female threads in the block you need a 1/8 bsp male to 1/8 NPT female, You can get these at a lot of industrial supply places such as MSC the aftermarket gauge and fittings will all be NPT threads

 

i actually dont even know how to measure it. is there a site or something to show me how to measure it?

 

which fitting are we talking about? and what year etc is this? if it's where the original sender screwed into the engine I can almost guarantee it's 1/8 BSP, nearly every Honda uses this for the oil pressure warning sender

 

This should be what you need, if you are changing the factory warning light sender to a gauge, this cahnges the BSP threads in the block to NPT which is pretty much standard for all aftermarket gauges
