Gauge Mounting: Do not install bracket and nuts until reaching step 8 in the For Mechanical Gauges section or step 10 in For Electrical Gauges section. PRECAUTIONS 1. Disconnect the battery ground cable before performing any electrical work. 2 Route all wiring away from linkages, engine parts that become hot, or moving parts. Never smoke while working on your vehicle and always keep a fire extinguisher nearby. I recently got around to installing the 1-1/2' Sunpro mechanical oil pressure gauge on my Yanmar 1700. The needle jumps around from the engine vibration pretty bad.
Many cars only come with an 'oil light' used to indicate low oil pressure. However, the problem with an oil light is that it usually does not come on until you are dangerously low on oil--not good.
Cars that have an actual gauge will usually have an electric gauge, which uses an electric sending unit in the engine to send a signal to the gauge through a wire. While the electric gauge has a needle that moves, it basically only tells you that there is oil pressure in the engine.
The best type of gauge is the mechanical oil pressure gauge, which physically reads oil pressure directly from the engine through a small plastic or copper tube. This is the most accurate type of oil pressure gauge; with a mechanical gauge, if your oil gets a quart low you will see it on the gauge. Daz3d - Poser - Young Teen 5 Characters And Poses on this page. 1 Locate the oil pressure sending unit on the engine. The location varies based on the vehicle. Look closely at your engine for a round, copper colored object about 2 inches long and as big around as a quarter.
It will have a wire connected to the end of it. Disconnect the wire from the sender.
Verify that you have found the oil pressure sending unit by briefly starting your engine. If you have a light, it will stay on; if you have a gauge, it will not move. Use a zip-tie to secure the wire to a safe place away from the engine, such as the wiring harness. Remove the sending unit with a wrench. 2 Locate the double male-end compression fitting in your new gauge kit. It has threads on both ends, and a six-sided section in the middle so you can turn and hold it with a wrench.
Look closely at this part. You will see that the threads on one end taper slightly. This is called a 'pipe fitting.' The other end is where you will hook your oil pressure line. Check to see if the threads on the pipe fitting end match the sending unit you just removed. If they do, wrap two turns of Teflon tape around the threads in the opposite direction of the threads, and tighten the fitting in the engine block where you removed the sending unit.
If the threads do not match, find one of the adapters in the gauge kit that matches the old sending unit, wrap it with Teflon tape and install it in the engine block. Wrap the compression fitting and tighten it into the adapter. 4 Route the tubing carefully into the passenger compartment by locating a place on the firewall where wiring runs through it.
The firewall is the rear part of your engine compartment, to which the brake master cylinder is attached; you may be able to slide the tubing through there. If not, choose a spot on the firewall and drill a hole. If you have to drill a hole, insert a grommet into the hole. A grommet is a rubber ring with a groove around the outside edge that fits over the metal.
This will protect the tubing.
Hey guys, I bought a little universal Sunpro 3 gauge pod with oil pressure, water temp, and volt meter in it. I got q's on installation of all 3. 1st, voltmeter, seems simple. Ground it and wire it in with a fuse box accesory. Seems simple. One thing, I have a cb wired into the fuse box and I have one of those accesorry fuses that has a wire coming out of it to wire things in.
