There is one on Amazon similar to yours but this one comes with a quick connect instead of a hose barb. It doesn't say how to get the hose connect though. Also the older one on Amazon is a little bit more in price.
The question is, why did UPR add a spring washer? don't they know what you guys are discussing? If the original was tight n secure then why? How did it improve the plug?
Also are those 2 O-rings permanent? or do they have to be changed like the stupid oil filter?
I LOVE that spot .... I copied you with a slight deviation. Instead of mounting/taping the foam to Velcro strips, I taped the foam to the slide mount of the detector. This way, my detector slides off like a breeze. Now lets see how long this tape holds up!
I have a Ronin as well but I've noticed using the black screw you're talking about doesn't fully drain the oil. I tried replacing the washer spring so i removed a the plug and about 1/4 of a quart started gushing out. However, I have to say that I tilt the vehicle to get more oil out.
