Bought an epr s475 over stock kit and was curious if I needed a different belt for my truck when I install? Heard something about a something smog being in the way?

There are two different belt sizes....one with the pump and one without. The difference is negligible though. You can just remove the pump abd not worry about getting a new belt.

I moved my battery to my frame today. Taking downpipe, coolant tank off and moving my fuel filter housing tomorrow. Will I have to buy any new fuel lines, or will all the lines work around it?

Where are you moving the filter to? You will probably need some 1/2" fuel rated line going off memory. Been awhile since I put one of Trent's kits on.

I would delete the factory filter completely and just make sure you have a 2 mic filter on your lift pump.

Bryce have you looked at Dexter's EPR twin kit on his lb7? Should be about he same and its a pretty simple install. Belt don't have to be touched.

Totally agree, if your lift pump is a one w/o the filters install one downstream of the lift pump on the inside of the frame rail, mount it on an angle so it doesn't hang down. Easy to change and you won't have to worry about the potential leaks the factory filter housing can get.

8" tip??? That gay as hell!!:roflmao:
