Ready to buy FASS but...

Two things:



1. should I wait for the AirDog (name makes no sense)?

2. Is there anything better right now?



Thanks

I don't know how much difference there is between the AirDog and the original Fuel Preporator (which has been around for a few years now).



The Preporator and the FASS are similar in design and function and I think either will suit your needs.

The difference between the AirDog and the original Preporator is scale.



As far as whether there is anything else in the aftermarket better... as of today... these are probably the best thing going.



The name "AirDog" is simply marketing name to catch attention. The biggest thing it does is remove entrained air from diesel. It also pumps and filters fuel. So the name AirDog is somewhat fitting I would say.

"DTT MECHANICAL FUEL PUMP



I've been very fortunate to have had this pump on my rig for some two months now. Being an Abbotsford, B. C. type (10 minutes from DTT and all the crew) and where it's easy to give and get almost instant feedback, I believe that the days of the "other" LP solutions will soon be history.



Think about it, a system that increases fuel pressure when RPM's increase - just what the 'doctor' ordered. This of course will require a major readjustment of what to expect when looking at your fuel pressure guage, LO versus HI pressures during idle and higher versus lower pressures when cruising - can't really do anything else 'cause the higher the RPM the more fuel the pump is pushing. What a novel concept - getting more fuel when that really expensive injector pump needs it. .



The OEM LP is still there. It'll be handy in order to prime the system after a fuel filter change or in the unlikely event you ran out of fuel. You could likely turn the engine over a few times and accomplish these tasks with the mechanical pump- still, a nice feature and because it runs briefly when first turning the key on you're ready to go as when the LP is functioning per design spec's. Should the belt that runs the FP fail the LP will come back on stream (it won't be running any other time, other than those maintenance requirements mentioned earlier, so should last the life of the truck) and you can change that belt in moments need be (you do carry spare belts don't you?).



As with most great ideas this one is "poetry in motion". Despite a mention earlier in this thread by, Edward, this is a really simple although well thought out and designed system with very few parts that will (has) make most of us wonder why we hadn't thought of it ourselves. I'd gone thru 3 LP's myself but am confident I won't need to purchase another unless somebody swipes it off the frame where it sits now. By the way, because it's no longer running all the time the noise factor is considerablly less - never realized how noisy that LP was until it wasn't running hour after hour - pure bliss.



Yes, there's a bit more to this system then what I've mentioned. I'm not the designer, just a fortunate user, so direct any queries you might have to DTT - this one is another of their many winners. "



As to if it is "better"? Don't know, both systems appear to have promises, cost is about the same. Best bet is to call each vendor and get as much info as you can.



Take care,



Casey
