What are people using for fuel pressure sending units? I read on glacier diesels website to use the Isspro -ISP-R8917-03, but it has two hookups on top, is this for when you are using a gauge and a chip like the quad that can read fuel pressure. The reason I am asking is, the quad only has one wire and Im assuming it just works like a temp sender does.
yes but the body of sender must be grounded unless the mount is.
