From the stealthmode website.
This is a Turbo feed and drain kit that uses a tuner toys block fitting and -3 stainless steel line (4ft). The block fitting, FOR HONDA MOTORS (B, D, etc...) has the correct 1/8 bspt threads for the oil pressure sending port. (Most oil lines come with 1/8 npt threads which are incorrect and may strip the block.) The same 1/8 bspt threads in the back the fitting for the reusage of the stock oil pressure sender.
Dual 1/8 npt ports are off the side of the fitting. One is for the oil feed line, and one maybe used for other applications (Gauges, ls/vtec, etc...). The drain consists of a tuner toys oil drain flange with a barbed fitting connecting the drain flange to the -10 stainless drain hose (14"). We use a barbed fitting on the lower end for the pan as well. Kit comes with everything you see.
It says it has dual ports and I don't see anything about couplings in the pictures or description.
What kind of gauge did you get? Mechanical???? I just got an Autometer oil temp and oil pressure gauge, both included senders that need to be wired up to the back of the gauge. Just curious!
