I tapped into the alternate plug, and on the back of the block, and routed the plastic tube thru my ash tray, the gauge lays in the ash tray itself, and I can close the tray if I do not want the gauge to show. Anyway the factory gauge was the problem. the new one shows good oil pressure all the time, while the factory goes up and down whenever anytime it feels like it. Ill change out the sending unit at a later date and see if that corrects the factory gauge. I was sure relieved when I saw good oil pressure all the time. Im new to the forum and really appreciate all the helpful people out there. Thanks Again

There is a kit available to you can just buy bulk tubing for it. Plastic is not a good thing to use. Very fragile and flammable/meltable if close to heat. Not legal to use in sanctioned racing.

An oil leak inside on your carpet ain't pretty live every 24 hour block of time like it's your last day on earth
