Update March 2014:
Looks like I used the product in the wrong application. The Amazon page says reads fuel or oil pressure, but the Holley page I just looked at says oil pressure switch. I was using this switch to turn the electric fuel pump off when the fuel pressure got over 5 psi. Worked great at first, but within a few hours of use or couple of weeks, it would just stay on and never shut off, even with pressure building over 10 psi. This happened on all three switches I purchased.
Either way, I have removed them and will just go with a relay off the ignition to drive the fuel pumps through external regulators. If you are looking to hook these up to a gas line, I would not recommend it. I believe Amazon has the wrong wording up above.
Still not happy with Holley. There higher cost pump had a chipped magnet in it that would lock up the fuel pump occasionally once it got warm. That was fun to figure out. The cheaper generic one from Summit in Ohio, you know the racing place in Akron, was much better.
The only issue i face here is the odd angles of the terminals. If your engine has an oil pressure line is closer the firewall, it's a little difficult to screw in the terminal screws because of the odd angles.
But as far as the function goes, this product is of excellent quality and it performs as intended once it's set up.

Thought this was the switch to get. I installed it and yes there is a nut used to tighten it and I didn't tighten it by the casing just in case anyone was wondering. Read morePublished 22 months ago by ClLy
