"Best" spot to mount FASS or Airdog pump?

[015point9]

Is there a "best" spot to install a FASS or Airdog pump?  Thinking closer to tank because I heard the pumps are better at pushing fuel than pulling.  What about cold weather? Any place better than another?

Eric at Vulcan Performance sells a frame mount kit for the FRRP.  He highly recommends it!

I've got mine tucked behind the transfer case. This keeps the blowing cold wind off it, out of the debris path from the front tires, also the skid plate protects the filters from road debris that might be kicked up.

My fass is under bed, held with a mounting bolt for the bed. Fass is much bigger then airdog and under bed seems to fit good.

I've install several FASS system but the filter are always still hanging in the damage path from the front tires. I've seen a few ranchers locally dent the filters from throwing stones from the dirt roads. All you need is one little hole and the system fails. I've also seen last winter where a FASS system froze up because of the bitter cold and was popping fuses not to mention it had gelling issues way more than my truck does.

15 years of bit cold winter down to -35*F and never gelled up once yet. This AirDog is heading for 12 years old and still pumping fuel without a single issue.

Op here...

Thanks for replies. 

Seems it doesn't matter if pump is closer to tank or closer to VP44?

I was under the impression these type pumps "pushed" fuel better than they "suck"

Fuel pumps push fuel, as the fuel is discharged (pushed) from the pump a vacuum is formed and atmospheric pressure pushes fuel out of the tank and to the pump the same way atmospheric pressure pushes fuel out of a tank when you siphon it. 

The fuel pump should be as close to the fuel tank as possible.

I know some people mount pumps in bed or tool boxes, but I don't like that idea because of fuel has to be lifted and there is more changes for cavitation.
