Guys, looking for input.

 

Current set up is stock lift pump on back of housing, Baldwin PF7977 in stock housing, then through a Donaldson P551313 prior to the CP3. Been running this for the past number of years and it's fine, just looking to get away from the stock lift pump.

 

I'm leaning towards the Fuel Boss, as it seems a more straight forward set up, but thought I'd ask for input here. I've heard the FASS pumps are loud. Can it be heard over the engine at idle?

 

Thanks

 

Dan

I am a mechanical pump kinda guy.

 

But I have been told that FASS and AIRDOG have made some advances in the motor design. Mostly hear more good about Airdog.

 

That said, I personally still protect a mechanical pump if possible.

I have had an AirDog on my truck for the last 8 years with zero issues ( knock on wood) I have always preferred AirDog sine they used to be a little less pricey. We never really sold FASS at the shop as they wanted us to sign a contract that said we wouldn’t sell any other system but FASS. Just out of spite we stopped selling them mostly for that reason. However, I have seen an even number of issues with both systems on trucks. I like the mechanical set up. Just never really need one.

Well, I run a mechanical pump and also the factory intank electric pump, a Baldwin filter in the stock housing plus a Cat 2 micron before the cp3. Oh, and a fuel pressure regulator with separate return to the tank. I've messed with this system more than I care to think about and it's still not perfect. Maybe I'm getting older, lazier, wiser, who knows but my line of thinking now would be keep it stock with a 2 micron added then carry a spare pump to change if/when it breaks. I'm not really sure if all my effort, time and money spent was worth it.

I forgot to add, if you replace the electric pump with just a mechanical one you won't be able to prime the system after a drain/filter change. I used a drill to prime mine before I put the intank pump back in the system. The mechanical pump was not able to draw fuel from the tank at just cranking rpm.

Here's my experience with after market lift pumps:

 

I put an airdog on my 99 shortly after I bought the truck (The stock lift pump had died). I ran it for 8 years and it never gave me a problem. I did have to swap out a spring to lower the fuel pressure a bit as it actually ran a little higher than I wanted.

 

On two different occasions I had problems with my fuel pressure readings on the gauge dropping, but both times it turned out to be a failed isolator. After the second failure I switched to a different style/brand of isolator and had no further issues while I owned that truck.

 

As far as noise? it was never loud enough for me to hear in the cab with the engine running. I could (barely) hear it run while waiting for the grid heater, before the engine started.

WTBS, I do wear hearing aids... :)

also Scott the years 98.5-02 VP trucks were the noisiest year injector pumps and therefore engines ... you can stand near the years 98.5 to 2002 and tell almost what year they are by engine noise I believe 2001 and 02 are the two most noisy ... so it's no wonder you couldn't hear the air dog LOL

 

I too am mechanical so I can't help you as you don't have the boss for a 12 Valve lift pump like I use. In order for you to have a mechanical you'd have to do one of the belt driven type and I don't remember if they are still available or who made them sorry no help

Airdog would last on average 4-5 months or 50k miles for me.

They kept sending me warranty replacements. Ran fuel conditioners all the time too. Plus pre and post filtration.

 

Im at 203,000 miles with factory pump on my 16.

I do know that this will eventually get addressed. I might go with dealer stock replacement as they offer two yr unlimited mileage warranty North America coverage.

I am running the original Airdog 150 that I bought new in 2008 and it has been on 2 different trucks. I also have been running the 40PSI spring for most of that time.

Also, I had a friend install one on his 2001 and it worked great for him but be aware that you can split the pump housing if you overtighten the fittings. He found out the hard way.

Airdog. Get the fp150 (original design) or the newest model (something something 4g)

 

FASS Titanium 150 if you go that route.

 

Cut the plugs off and solder the connection to the pump on both units. If you are running high pressure (Im running 75psi), expect to replace either unit at least once every other year.

I have about 120K on my Airdog, zero issues. I had about 150K on my FASS in my Ford, zero issues. Only complaint was the FASS was a bit loud, but the newer ones are quieter.
