FASS Install question

[PRout]

Will be installing the FASS system soon.



One question:



Is it practical to keep the original fuel filter inline?



I'd prefer to keep it inline for 2 reasons:



1. Filtering close to the VP44. (alot of distance from the FASS).

2. Reliable fuel heater close to the VP44.



The drawbacks seem to be reduced fuel flow, and can the original filter handle the increased flow rate of the FASS?



According to Brad, he recommends going straight from the FASS to the VP44 because this thing flows ALOT of fuel, and has its own filters anyways.



This way you can remove the orig fuel filter assy, and have more working room next to the motor.



Another option would be keeping the canister for water seperation, & fuel heater, and removing the filter element.



So, is it best to go to direct to the VP44? Or leave the inline filter in place, and upgrade the line from the original filter to the VP?

Shortshift, personally I would go straight to the VP44. Don't worry about the stock system anymore, consider it gone. I haven't taken off my old lift pump/ filter yet but when the weather warms up some I will. I did however leave the stock line there,( not using it) and just plugged the lines. I will have it all removed in the future, just too darn cold out.



Now, if you decide to leave your filter on and leave it in line, install a fuel pressure gauge and let us know how it turns out. Shoot, maybe you will find out you can and if it works and makes you feel comfortable, then try it.

The FASS has its own water sep. so I would not worry about that. As far as the fuel heater goes, I don't think it gets cold enough in s. California to really need it. My truck has done fine down as cold as it has gotten around here about 0, not that cold I know, but I don't go too many places it gets much colder. Besides I alwayy keep an extra filter with me in the winter time incase it does happen. Dean

We do travel to places where it gets cold, so do want to keep a fuel heater if it is practical. Might use the heater on the FASS itself if it is an option.



Im thinking about piping the FASS to the inlet of the OEM fuel filter, and upgrading the lines from there to the VP44.



Also, was thinking the original lift pump might make a nice transfer pump for moving fuel from the aux tank to the main tank... And if there was ever a problem with the FASS in the field, all you would need is some hose & some clamps, and you could be back on the road in short order using theoem lift pump as a back up.



Just examining the options as there are lots of ways to go here.

Keep us updated as to what you actually do with it.

I have a reman lift pump with 20,000 miles and a factory filter (99) sitting in my shop. The stock banjo bolts on the factory filter will restrict fuel from the FASS. Why no use it the way it was intended? Its a great system-now I am working on longevity.

 

[PRout]

Right, probably is best to keep it simple and go direct to the VP.



Also, I guess you really dont need a fuel heater if you have enough anti-gel additive available.



Think Ill remove the oem fuel canister, and that should free up some room, then work on converting the oem lift pump into a transfer pump from the aux tank to the main.



Im thinking with the way the FASS pumps into the vent tube the way it does, it might really slow down the gravity feed system from the aux, and it might require a txfr pump to move the fuel while the FASS is pumping into the same place.

just put FASS system on mine there is a fuel heater on the FASS. but why do you need it in cali. im in ohio and the dealer up here said not to worry about the heater they are not having any trouble with the ones they have installed. love the system 17psi at idle and at WOT it dosent move.
