I'm reaching out to other members to understand how they've mounted their oil pressure sender. I have an autometer oil pressure gauge as one of my gauges and right now the sender is remotely "mounted" by zip-tie to the wiring harness behind the engine. I want to mount it more securely to the firewall to a bolt or such (I can make my own bracket).

I have line which comes out of my oil filter housing as you see here.



Here is what my sender basically looks like (picture from the web)



The question I have is this, the wire going from the sender to my gauge attaches to a little nut on the top of the sending unit. Obviously if the nut touches ground it will short out the voltage to the gauge and the gauge will either peg high or low - is it OK to use a bracket that hugs around the sender? I was thinking of welding something up with aluminum to hug around the sender so I can mount it on one of the bolts on the firewall. I was thinking above the steering rack area to the passenger side of the transfer case side of the firewall. Obviously the bracket will be in electrical contact with the body of the sender- but I am assuming the body of the sender unit is not electrically conductive with the nut on top right? In other words, will I have to electrically isolate my bracket from the sending unit/car? I assume I am making a big deal out of this for no reason- but I'd still like to hear what others think, and if anybody thought of a better way to mount it.

 

I used the STM oil line, similar to whats pictured, and zip tied the sensor to something in the engine bay also lol

 

My sending unit is mounted near the stut tower/ABS lines. I wanted it far from engine heat/vibration but still in the engine bay. I wrapped it with rubber for isolation and used hose clamps to mount it to the ABS bracket.

 

I used the AMS oil line and mounted the sender using a 1.5" P-clamp bolted to the firewall.

 

mm... I like your idea.

what do you think of those?

I assume you used an OEM fastener for positioning, do you remember which one?

 

I threaded my sensor into the block directly where the stock oil pressure sensor is. This keeps it away from everything.

 

Except they typically break and/or leak when mounted to the engine.

 

I got the Greddy Oil block adapter...then ran the AMS sender line to that and then the sensor reads from that. Not sure how that last part is mounted since I didn't do the work but haven't had any issues with it in nearly 10ish years of DD and tracking.

 

Yup, those are the clamps. I ended up having to cut the rubber into sections to allow the clamp ID to be big enough to clamp my sender. I am not going to be home for a couple more days to confirm but I'm pretty sure I used one of the studs where the wiring harness comes through the firewall. There's not many options when fitting it up due to the length of the AMS line.

 

I'm wondering if I should try the 1.75" version instead of the 1.5" so that I'll have a little extra diameter to avoid the problem you had...

 

Only if You have the wrong thread. The block is bspt. I also run the aem sensor which is small and I do not have the stock oil pressure sensor.

 

I took care of this today. I did almost exactly the same as described above. I used the stud on the left of the picture which has a plastic fastener holding the dash-pad on. It is threaded m6x1.0. All I had to do was install a nut.
