you should have said something, i got a set of trucker mirrors that fit this body style much better. these ones you got look so wonky and out of place, it ruins the look of the whole truck.
the only way i can see suffering with these is if you were hauling a extreemly oversized pickup in bed camper.

Thanks Grinner, that is correct... back-up till you smell ***** and hear glass... That's what my old boss use to tell me.
I was stoked when I found them. They are refurbished brackets, new hardware and NOS mirror heads (still in the box).

I Use PTFE Paste, used for multiple applications in plumbing, its oil,gas,and diesel fuel safe along with a bunch of othe chemicals. I used it on my transfer case fill/drain and my axle fills, plus I put it on my oil pressure sending unit because I was getting leaks like your's. Hope this helps

Been a while... But finally built a bracket to hold the Oil Pressure Sending Unit and the Hobbs Switch. I'll change it up later, but it'll hold it steady for now.
I would really like to hook up a primer switch for the fuel pump because it still took a while to get it started after sitting for a little over a month.
More to come.

You could always stick a time-delay relay in parallel with the oil P switch, so you get a second or two of fuel pump operation at key-on, regardless of oil pressure. Duplicate the factory behavior of EFI pumps...

Would I need to add another relay to the system, or is there a relay that will control both the timed power and the oil pressure dependent power?

I haven't done research into what OEM fuel pump control modules/relays might have the functionality built-in; there could be an easy swap option out there.
I was thinking of adding an additional timer+relay in parallel to the oil pressure switch. It would have to be a one-shot, normally open timer & relay. Desired behavior would be: when ignition switch hits the run position, close the relay only for a second or two, then open it again and wait until the next time the switched power from the ignition goes from off to on. This new relay would bypass across the oil pressure switch to energize the existing fuel pump relay briefly even though there's no oil pressure.
Something like this could work:
TGPB | Single Shot Relay Timer
but since it's triggered by external dry contacts, you'd have to have a NO relay switched by the ignition that would close those contacts to control it. (i.e., it'd be a standard relay plus this)
Or something like what this guy did would work for the timer circuit, but again it requires an external relay switched by the ignition (in his case the ECM, but you could use a standard relay to switch a ground at ignition on) to control it too:
How to build a Primer Timer and cure your Viper Fuel Pump Starting Problem
So you'd end up with a fuel pump control module somewhere that would have a relay switched by ignition power that initiated a timer circuit, and the timer circuit would control a bypass around the oil pressure switch to energize the fuel pump relay. Sounds complicated, but it's essentially two extra devices: a standard relay and a timer. Or again, it's possible that some OEM junkyard part from an EFI car would be appropriate, but I don't know specifically what.

Think this one would work?
TDR-M: Momentary Variant of Time-Delay Relay
If I do something like this, do I need to put something in the lines to stop from feeding power through the opposite circuit?
