So four stops later I'm at the tire shop kinda hoping I picked up a nail or something, but nope, it was the stupid TPMS I paid $385 for!

Anyways, I still want the ease of mind knowing the tire pressure is safe when going 70mph, so I want to replace this one. Any suggestions?
I understand your frustration. I've had my flow thru 507 system for about 2 weeks now. I was also very frustrated but I believe I found the issue with my system losing air. I was so concerned with over tightening that I had not tightened the sensors enough. Once I tightened the sensors all the way not just slightly past the hissing sound all seems to be good. Apparently tightening the sensors can be a little more sensitive then I thought it would be. Good luck!

I put TST 507 flow-throughs on GT and my Jeep Liberty toad. Quite to my surprise, half of the sensor and all of the stem sick out beyond the wheel rims on the Jeep! One week after putting them on, I accidentally bumped one of them and it snapped off the aluminum stem. Thankfully, it snapped off above the valve. So the tire stayed inflated. $100 later, I had a stainless steel stem and was back in business. This may be something peculiar to a Jeep Liberty, but check on your own toad if you have one and see if it sticks beyond the tire and wheel profile.

Couple of things that I found on my e450. I installed the passthrough tire pressure system and did loose inside pressure.
I have the plastic valve stem extensions .
The reson for the loss of pressure was two fold.
1 tightness of the Allen screw in the stem
2 probably moving the extended stem

Solution is very simple. Thread Tape.
What I did was remove the outer rims thread tape the extender bottom and top. Attach the tire pressure valve tighten and secure the Allen key. Yes put the outer rim on and correctly tighten all well nuts.
I have had no pressure loss over the last 2000 miles

I have the eezrv system, almost went with the TST but liked the display on the one I bought more. Both have high and low pressure alarms and so far I've been very pleased. As a prerequisite I did install chrome valve stems on all six tires, as it was suggested her in the forum.

Again, thank you to all for the information. I'm at the stage now where the dealer is telling me they don't have a tire machine so they can't bolt in new metal stems. So I called up Discount Tire and they don't stock what the Sprinter 3500 w/Dual rear tires needs.

Can anyone point me in the right direction? Perhaps with a link or brand/model #? I'm looking at Amazon now and there's so many options I just don't want to order the wrong thing and have another set back. Trying to get this done before Labor Day!

My goal is to make the TST 507 TPMS work with metal stems/braided extensions for the inners. Heavy sensors are flopping around on the rubber extensions and causing leaks.

Thanks in advance!

That's where I got mine. Called prior to ordering to verify that I was buying the correct stems. Very helpful people.
