FASS Fuel System

I would like to address the installation of the FASS System. We are changing the mounting bracket to adapt to shortbed and longbed 1994 and up Dodge's. Our difficulty came not from mounting to a longbed but to the shortbed's. We have now solved that problem and it will mount in about 1. 5 hrs. Another problem we have address in this same category is that we will have pictures in our installation manuals in about 2 weeks.

What size of fuel line comes with this kit? Where can a person buy a a larger pickup tube to mount in the fuel tank to make sure it sucks as much fuel as the electric pump can take?

 

[Ncostello]

The Tube going down to the bottom of the tank is 3/8" basically. I'd just remove the screen mesh inside the tank at the bottom of the pickup and you'll suck as much fuel as you'll need. Thats what I did.

I have heard this system only has about 25 PSI. Sounds great for 24 valve, but what about Hi-Po 12 valves?

I'm running 60 PSI right now, and the thing finally seems to run the way it always should have, hate to lose the extra pressure.





How are these systems holding up, Brad?

Sled Puller,

I think you are right about the pressure. That is the number Brad told me when I spoke to him on the phone about these. Is EE installing them on any Hi-Po 12v's or only 24v's?

FASS Fuel System

This is to reply to some of the questions dated 10-15-03 and newer. 3/8" fuel lines comes with the FASS unit and the stock fuel line inside the fuel tank has been more than sufficient to allow the correct amount of fuel to FASS unit. Since putting the unit on I have never had to drop the tank to get the correct amount of flow to the injection pump. I am not saying that putting a large draw tube wouldn't help but I think there will be very little benefit to doing so if any benefit is achieved. The FASS unit is excellent for the 12 valve's as I have it on my own. I have performed massive work to my engine all the way down to the crank, if I want to (which I have only done 1 once) taken it over 100psi in turbo boost my fuel pressure gauge moves very little. Keeping plenty of pressure in the P7100. If you are running 60 psi to the P7100 you can supply your high pressure pump with the FASS and gain more pressure or you could set our to about 30psi to your injection pump and I'll bet it'll run better @ 30psi with no air than at 60psi with air in the fuel. Also, with your engine turned up like I am assuming the FASS will give you more power but at the same time lower your egt's about 200 degrees.

So you can adjust yours up a bit then?



Before I put the aux pump on, my fuel guage would idle at about 18 psi. Then drop to zero when you mash the throttle, the smoke would even clear up.

I don't need the 60 psi, but the pump was cheap, about $60, and fit right in.

If the FASS can sustain 30psi at full throttle, that should be enough, I would hope.



Evidently, air in the fuel is a bigger problem than I thought.



What is the estimated service life of the FASS unit?

The only thing to go out on the FASS Fuel System is the fuel pump. The fuel pump will last about 600,000 to 800,000 miles. Of course the filters will need to be serviced before that.

I was wondering if anybody could give me some dimensions of this unit? HxWxL thanks.

 

[wsteffes]

Height - top of pump to bottom of filter 14 -14 1/4 in.

Width - just the unit 4 1/2 in, with mounting bracket 8 in.

Length- just the unit 8 1/2 in. (inlet, outlet fittings add to the length)

Has anyone noticed any difference in how quickly the engine starts after installing the FASS? Mine seems to take a couple of turns of the engine before actually starting. I just got the FASS on Thursday night. Before, it started if you did anything more than the slightest "bump". I don't know if the two are related or not, the FASS is just the last thing I did to it (the only thing since getting the new block installed).



Thanks,

Chris
