This fitting screws into your oil pump to create a 1/8" NPT port for an oil pressure gauge. It can also be used as an oil feed line for your turbo ONLY if an inline filter is used. I'm also including a 90 degree stainless steel 1/8" NPT to -3AN adapter. As you can see, the parts are used, but they've been cleaned in rubbing alcohol. Asking only $10 for the pair. Shipping and Paypal fees are not included. Send me a PM if you want it, thanks.
