Fass Or Airdog
 

whats a better fuel system a fass or an airdog and what reasons are there that one is better than the other....? your advice is greatly needed and appreciated, im stuck here and dont know which to choose, thanks

They are both excellent pumps and both include a lifetime warranty. I have had more issues with Airdog than I have with FASS. Airdog is less expensive than FASS. The Airdog is also a smaller and quieter unit.

do u have to put a draw tube in for both pumps

Ya don't HAVE to with the airdog,it comes with the little ma-hoosit (technical term) that connects to the top of the tank,I bought the 150,so if mom decided to go for the 600hp:D mark I could install the straw.

This is the most common question I get asked.

The differences between the systems are pretty minor. The biggest one now is pump size and line size.

Either way, you are better off than stock!

The tank fitting is a dorman connection. And while the manufacturers do not say you need a draw tube in every application, I recommend it for EVERY install. Again, this is just my opinion.

i would also reccomend a draw straw be put in, my fass 150 was installed before i bought my truck and the previous owner did not install a draw straw, under wide open throttle, itll suck the factory line dry and result in a temporay loss of PSI, im going with a 1.2 inch straw and lines all the way up to the pump, eventually im going to get even bigger factory injection lines from schieds too.
