Sending unit

[stemar]

Hello and Happy new year,<br />I bought from overtons water pressure gauge but they don't sell the sending unit that attaches to the engine. Can you please tell me a site where I can order it.<br />Thanks

Re: Sending unit

Bondo<br />Don't you need the sending unit so you can attach it to the engine and then wire it to the gauge??

Re: Sending unit

stemar,<br /><br />If you have a water pressure guage, there is no sending unit. Most use a plastic or nylon tubing "tee" that splices into the telltale line.

Re: Sending unit

Sorry guys,<br />But If I understand well although I have the gauge I don't need the sendimg unit and instead I can use some other ways to make it work. I have 1989 Mariner 90 HP.<br />Thnaks again

Re: Sending unit

stemar,<br /><br />All you need is some tubing and a "tee". <br /><br />The tuibing inside diameter should be the same size as the outside diameter of the nipple on the back of the guage. <br /><br />Then, you will need a 3-way tee to tie into the telltale line on the engine. An automotive vacuum line tee will work fine for this as well as automotive vacuum hose.<br /><br />The tell tale, on the back of the engine has a discharge line going from the cylinder head to the outlet. Simply cut and splice the tee into that line. The open end of the tee goes to the guage.

Re: Sending unit

Only need to hook up electric if you want the light inside the gauge to work at night when you turn on the navigation lights...
