FASS fuel system

This is a list of filters.

I'm pretty late to this thread but I have one on my 12.7 detroit. No mpg gain but better engine response and engine use to hesitate when I shifted to high side but know picks up and takes off right away.

 

Here is how the owner of FASS diesel fuel systems spends YOUR money.
And he gets his just desserts.

 

I put one on my 2006 Century with a MBE4000 Mercedes 450 hp.
Never noticed any improvements. But twice it blew out the seals on the main fuel pump spilling fuel onto the ground out the weep hole.

 

Oh wow. Talk about a mess

 

i think i see the problem... the guy on the boat didnt lean far enough to the right(starboard for you nautical types) to compensate for the turn and bowing trailer.

 

Would recommend that he stay out of the heavy haul business, although this might have been a hired truck. Haywire anyway.

 

Think about this, if it truly made a difference then it would probably be installed from factory. It is in the mfg best interest to lower warranty claims and decent performance. But tried on a Cummins in a dodge. Didn’t see much difference. But then again it was straight stock
