There are MANY choices for your fuel transfer pump (pump moving fuel from tank to engine/Cp3 injection pump)



But theres where the can of worms pops open. Depending on what you want to do with your truck and how far you plan on taking it HP-wise, etc,etc



And many of use have multiple ideas of which one is best...



Heres what I see alot of: (in no perticular order)

1) FASS with filters

2) FASS "2" -- the pump without filters

3) WALBRO EFI pump with bypass regulator

4) Holley Blue

5) Carter

6) AirDog system



I suggest the walbro based upon a multitude of reason - Cost,noise,flow,easy of replacement,easy to upgrade



Yet the FASS (with filters) is certainly a fine product and the air-seperating ability claims to make more HP, etc, etc



In the end, I would suggest going to a few local truck pulls or events and talking directly to people with these sytems and see for yourself the product...

Nothing but good things said about this system. It runs at only 20% capacity. Runs around 17psi and only drops to around 15psi at WOT. I don't have it yet but have done some home work

No it isn't the best! The best in MHO is the Mitusa! Forget electric, they eventually burn out. Mitusa is a mechanical pump. Get ahold of Opie on the Northwest Bombers. He will fix you up!! Price is about the same as the Fass.



I've had mine on since last December. I idle at 35#'s and at 70 mph I'm at 50#'s. Now that's higher than what he usually sets the Mitusa up for but I wanted more pressure. The pressure is adjustable.



The nice thing about the Mitusa is that the stock pump is still in the system so if you do have a problem with the Mitusa, the stock pump will take over. This way you don't get stranded!! I put a LED in the cab that tell me when the stock pump is running. It runs just at first till the Mitusa makes 10#'s of pressure then it is shut off by a Hobb's switch. So if the pressure goes below 10#'s the stock pump will kick on. No more getting standed!!

Glacier Diesel Power and Walbro pump... I don't care if it is electrical. If I had to start over from scratch thats the way I would go. The pump is barely working at load and replacment is a snap.

I like my Walbro. Customer Service at Glacier Diesel Power is great also. Jeff

What if your stock lift pump dies?

The FASS is pretty trick but their warranty and customer service can definitely be improved.

Put another mark up for The MITUSA

 

[Prairie Dog]

FASS is good but a little noisy IMO.

So we can still mount a mechanical pump like the MITUSA? That would be the best!

Does it mount where the old mech lift pumps mounted on the first gens?

im goin with the walbro so glacier diesel gets my vote. if you other guys are worried about more electronics go buy an old mechanical 12v then. just my . 02.

Ive had a cheapy carter pump for over 3 years, working flawlessly and now that I have a rail pressure gauge I can see that it is still working perfectly. Pump costs about 50-60 bucks maybe even cheaper I cant remember.

A couple of things to think about, first, the stock lift pump in conjunction with the Mitusa is only used when you turn the ignition on and the heat grids cycle and at start up until the Hobbs switch see 10#'s of pressure, the Mitusa make 10#'s very quickly, so the stock pump isn't running but a very period of time.



Now, having said that, for you to be stranded, the Mitusa would have to fail, (and with the LED installed you would know it), if you failed to fix the Mitusa the truck would run like it always had on the stock lift pump. Now if you didn't fix the Mitusa after the warning, and the stock lift pump fails, well who's fault is that? :-laf



One thing is that you will not be stranded if the Mitusa fails, where will you be if the FASS or Walbro fail? :-laf



Another good thing about the Mitusa is that you can not hear it! Not at all!!!



I wish the Mitusa had been out when I have the White Obsession (99 CTD), I was replacing the Mallory Marine pump on it every 6 to 12K's. I got real good at that, only took about 15 minutes and I had always carried a spare.

Scotty,



No it doesn't, the 3rd gen blocks do not have the mechanical pump holes.



It mounts right of the front into the oil pan bolt holes and has a pully you install on the crank which will turn the cog belt that operates the Mitusa.

Where will I be? I'll be laying under my truck for about 15 minutes while I swap out the "dead" Walbro with the spare that I carry behind the back seat. After that, I'll be on my way down the road. $109 for a spare Walbro pump on eBay; can't beat that.

Been there, done that! That's why I have the Mitusa! :-laf The electric pumps always seem to go out at the most inconvient times, snow in Spokane, rain on the way to BD Dyno Days, on the way to an appointment, etc. :{ Now I don't have to worry about it, I will still make it to the activity and work on the truck later. I have no doubts that the Mitusa will out-live any electric pump, that's one reason I chose it.

 

[FUL POWER]

I have the FASS on both of my trucks, i wouldnt have anything else, i have had no problem with either of them ever but i wish that you could talk to some one at FASS. I had going through dealers, i like to talk to the people directly... Thanks my only down side

YUP - had a few "incidents" related to the WAY the Carters were installed, but never any failings of either the stock LP - or the added Carter pusher - still have the originals, both operating perfectly. I hope my brand new replacement spares don't rust out waiting to be pressed into service! :-laf :-laf

Forgive me GDP.

Our GFS kits leave your stock fuel system in place and available for use at any time. Thru the use of factory style Deutsch connectors you can revert back to your stock fuel system by merely swapping electrical connectors at the tank.

The hardest connection to remove on the tank are the fuel lines. The electrical one is not real hard.

That is everyones fear, you can't tell when the stock pump will let go. Lots of times the vains inside the stock pump stick, therfore no pressure. My question would be could the mit pump build enough pressure from cranking. I am not a fan of the mits pump for the above reason. The stockers are junk. I have Fass systems on my trucks and no Fass related issues. If I had to do it again the walbro pump would be considered. The Fass has a nice clean install with filters. I wouldn't ever go with just the Fass pump.
