I have used one before and have installed a few they work great.

Did you notice a power or fuel milage increases with the installation of the FASS pump?

You will see a power increase if you are 'underfueled' now because of a big chip/programmer without suffiecient fuel delivery, but not on a stock truck...

I ran one on my 06 and it made a huge difference with a Juice/Attitude box. With the box on zero, I could not tell a difference...

Not intended to do anything for mileage...The box increased my mileage

longhorn is correct if you have mods done to boost your fuel input then the fass or airdog pump will work real well for making sure you are not starving the fuel rails for pressure but on a stock truck you probably wont notice to much gain

No fuel rails to starve on a 2001.

If you dont supply the VP44 with clean fuel at a proper supply volume and pressure you will wreck your VP44

If I was you I would do the FASS 150/150 get the maximum filtering and water sep you can get.

The 150 will also supply you a enough fuel for upgrades inthe future and might save you from buying a VP injection pump.

If your stock pump is under 10psi at WOT stop driving it and replace the lift pump or you will cook it!

thanks for the replys guys, i have seen on a couple diesel sites that people were saying they were worse than stock and failed right away, so im trying to decide if i should just save up and get the full system, this one just looked nice cause of the easy installation

For now you could also just get a big line kit from your filter to your vp44 to open up so the fuel can flow better and isn't restricted by the factory small diameter line.
