Default Oil pressure gauge

Two questions for those of you that have installed an oil pressure gauge. What size fitting goes into the case where the stock sender is? I believe it 1/4" but I want to make sure. Next question is for those that have the gauge mounted on the rear rocker. How long is that piece of hose? Russell makes a pre assembled stainless hose for that but I can't find anywhere how long it is. I want to use it but need to know its length because I'm not mounting my gauge on the rocker box. Thanks

1/4" NPT on the case side. Length, I don't know.
I mounted mine to my LR dash.
You can use 1/8 copper tube. Cover it with 1/8 rubber vacuum line to make it disappear (black)

Just wondering monster, is there a need to moniter the oil pressure on a 124" build vs a 107" build like mine? Making me think if I should be looking into this. Sure wish the oil pressure went to the ECM, I would display it on my Power Vision but for some reason HD must not think it is important to us...

An "idiot" light is cheaper, just like Chinese bearings, where you need dependability the most.

It's just a little protection for the money put into the motor. To me the $100-$150 is well worth the protection on a $5k+ motor. I don't think the idiot light comes on til oil pressure drops to 2 psi. Theses motors don't put out a lot of pressure but if your banging through the gears you'll notice the drastic drop from 30 psi to 0 and shut her down

I wouldn't recommend copper tubing. Copper will break due to the vibration of the rubber mounted motor. Better off finding a flexible stainless steel line.

So i guess SS is more flexible than CU?
I've used both. I have 1/8" SS inside my rubber hose now. Never had a problem with CU though that couldn't be repaired. If it does start leaking it's not like rubber where you get a catastrophic failure & loose all your oil at once.There's lots of things that COULD happen to a bike...

I read though that thread but the pic of where mud mounted his gauge is deleted. I thought about using copper tube but I'm going to mount the gauge on the riser tube of my tbars. I was worried that the twisting back and forth would be too much stress for the copper. Last thing I want to do is break that line and blow up my motor because of the oil gauge line. That would be ironic. I just bought some stainless braided 4 AN hose and the fittings I will need. Going to wait til I put the motor back in to get a final cut on the upper side of the hose. Holy crap stainless hose and fittings are expensive..
