Help! I just tried tech support at Quadzilla but they closed about 15 minutes ago. I bought the fuel pressure sending unit for the Commander but I'm sure this applies to other sending units as well. The included instructions are for '03 and newer trucks with the lift pump located in a different location. Where do I plumb the sending unit into the fuel system? At the tank inlet side of the lift pump or the outlet side? Can I plumb it inline at the injector pump? Is there a place that's both:

a) easy to access
b) accurate as to pressure readings?

Thanks!

Edit: By the way, I'm not sure if it makes a difference or not but this particular sender mounts to a banjo bolt, not the filter housing or anything.

After the lift pump but before the main/injector pump , I think most are doing at or near fuel filter , if I could see , it would be easyer .
Not after the injection pump [ pressure too high ] and not on the return line .
You want to be reading the lift pump pressure .

Best place is on the clean side of the fuel filter so that you can see any filter plugging.
