any thing besides the tank and fuel filter for them to realistically check?

 

i use to run a 45 gallon tank under my tool box that i told them was to a pump out on a rig they never realized that it ran to my actual fuel tank, they never did check it though thankfully enough, but all i have ever heard of them checking is just the tank

 

why did you end up getting checked

 

i have heard there is a way for them to test the exhaust. I dont know if its true but the way it was explained to me was that the dye leaves a trace in the exhaust and will show up in a reaction like when you use litmus paper

Once again I do not know if its true or not.

 

I heard the tailpipe thing, too. I wouldn't run red on a bet, way too much at stake! Fines in Az are huge!!!!!!

 

i never have, they just questioned me about it when i got stopped for window tint, mud flaps and fender flares

 

i understand the window tint... but mud flaps and fender flares???? were you excessivley blocking debrie from other drivers???

 

Probably lack of flaps and flares

 

yes lack of, my truck is stock height with just some 305/55/20 tires and they swear its lifted

 

DOT doesnt bother swabing the tanks anymore they just pull you fuel filter. i second dummy fuel filter in with diesel in it, that is first thing you see the other is hidded so when i do run died is virtually undetectable
