I know it's probably supposed to be so easy for you damn mechanical savvy people... But I suck at mechanical, that's my motivation to persevere, and I'm addicted to learning..

I CAN'T FIND THE OIL PRESSURE UNIT, so I connected an electrical fuel pump last night with filter before and after... I'm gonna tuck it up all neatly tonight, but I need some power to it, I searched and found good stuff on here, printed it all... went through my haynes, and the book doesn't mention the oil pressure sensor anywhere else than the wiring diagrams.... I think it's suppose to be located back of the engine, driver side, BUT WHAT AM I LOOKING FOR !!!

The book shows power going to it, can I splice into it with my fuel pump hot ?

Thanks Buds...

What Engine Do you Have??

Low Riders are for Boys that can't get it up!!

on either the AMC 258 or AMC V-8s, the oil pressure gauge sending units are on the passenger side. on the I-6, its behind the distributor. on the V-8's, its on the side of the block behind the front aluminum cover. i assume you are trying to wire your fuel pump into a oil pressure switch so that if you lose oil pressure (roll-over), fuel shuts off. i think you will need an oil pressure "switch" instead of a sensor. hopefully someone else has done this and can help you out. matt

AMC 360 '78-79 in an '89 YJ that was an I-6... yea, that's what I'm looking for, but I think I'm gonna just wire it to get it going for now, and find out more about the pressure switch thing, sounds complicated... unless some nice bud would write me a little walk through of what I need and how it's done... thanks a bunch guys..

This is a job for CJDave. I don't know if he is still around, but he uses the oil pressure switches for many different things. I'll look through some of the old post I printer out over the weekend and see if I can find an example.

Frank, see my other answer to your post... you don't want to hook to the oil pressure sensor... you want to connect the fuel pump to the Oil Pressure Gauge 12 feed wire....

an accessory spot in your fuse block will also work.. they are usually only 12v when key is on and start.. get a little electrical light tester.. about 4 bucks.. and clip it to ground.. and stick the pointie end in the acc open spot in your fuse block.. you should have atleast one.. unless you put something else there already..
you can also use the guage.. wire.. the other wire will go to ground..

Hey Jeepgod, look at those accessory voltage points with an Ohm meter (of course with the battery removed)... If I remember correctly these points are affected by the turning of the key from and to varied modes. As example if Franks fuel pump were connected to the ACC circuit, when the ignition key moves from START to RUN mode there would be a loss of voltage to the pump during the key movement. This could cause problems... and besides, do you really want the fuel pump to be pumping fuel when the engine is off and you only want auxilary circuits operational?

mmmm... i havent had mine hooked up that long.. my mech. fuel pump died on me again last week.. it was a mere month old.. so i went with the electrical unit.. and since i was on the side of a highway.. i just stuck it into the acc circuit.. i havent had the jeep in the run mode.. yet.. but i dont have problems with going from start to run... in fact.. hold on.. the other day at the baseball game.. i had the key turned so the stereo would run.. not the turn back mode.. and it wasnt running.. hold on.. ill run out there and see whats up.. yep its on.. and it doesnt seem to be doing anything.. no gas going into the carb..
is it really bad to run it like that.... its my first electric pump.. so.. im open for change.. [img]/wwwthreads_images/icons/smile.gif[/img]

Pat you should have it hooked to a oil pressure switch. Just in case you do roll or even if you loose oil pressure going down the road it would stop pumping. Were i used to work we had a bucket truck go over on its side (some smart guy didnt think outriggers were needed Hum i wonder why they put them there then). By the time someone could get to the truck it was to late and she seized up. What i found was that the electric fuel pump keep running a kept feeding the engine fuel. So the next couple of days i got to do a engine swap (lucky me) and we were short one worker.

Can someone please bring me a hammer my 33's just ate my fender again. Damn i need more lift.
