Does the flow thru 507 work good, or do they take air really slow? I have the 507 that you remove on the truck but they sent the wrong ones for the fiver.
I've got the flow-thru sensors, hadn't noticed a reduction in flow when adding air ... but then again, it is generally only a few psi that I need to add as the trailer is used on a monthly basis. In fact, thinking about the time to add a few psi to the TV tires, I'm hard pressed to suspect there is much difference.
