Can I run my FASS into the stock filter housing??

[mayfair]

I just got my FASS delivered the other day and I going to install it tomorrow. I'm installing it on a 98.5 24v Ram. I got the 150/95gph FASS.

I was thinking about installing the fuel line into the stock fuel filter canister instead of running it directly into the VP-44 for 2 reasons.

1. The fuel heater is located there.
Even though it dosn't stay cold here long ( I'm in PA ) it does get cold and I feel more comfortable having a heater and not needing it, rather that needing a heater and not having one. Make sense? I know there are ports on the FASS for heater lines. but wouldn't running the fuel line to the stock heater be easier and make more sense since it heats instantly instead of having to wait fo rhte engine to warm up?

2. The WIF ( Water In Fuel ) sensor is also located in the stock fuel filter canister.
I know the FASS has the water seperator, but the stock sensor is located in the stock fuel filter housing. I'm thinking that by keeping the sensor "wet", you'll also be keeping it "happy" and thus you shoudn't have an idiot light come on on your dash or you won't start throwing codes.

I was planning on running the line to the stock filter housing, but remove the stock fuel filter. Pretty much just a bowl of fuel that heats the fuel and keeps the WIF sensor happy. From there, the fuel would continue to trave to the VP-44 jst as normal.

Does all of this make sense, and do you see any potential problems by plumbing it this way?

Thanks in advance !!

You can route it there just fine. The problems start when you run high pressure (like on the CR motors) and you can blow the lid off the filter bowl. At 15psi, you FASS should be just fine. You may have to locate some fittings yourself, though.

It looks like the elbow fitting ( that comes with the FASS ) that you would normally screw into the VP-44 inlet would also screw into the banjo fitting on top of the filter housing. I think I'll be fine as far as fittings go.

The stock fuel path is:
From the tank
to the fuel lift pump
to the fuel filter ( containing the heater and WIF sensor )
to the VP-44

FASS's instructions show going from the FASS directly into the VP-44 eliminating the fuel filter bowl ( thus eliminating the heater and the WIF sensor )

I'm just looking to keep the heater and WIF sensor operating as normal.

Basicaly I guess my question is .... Why did FASS eliminate the heater and the WIF sensor in the first place? Am I not seeing something?

The wif is not needed as it has a good water seperater on the pump. The heater is just one of those things that can help a truck if it is in a very cold place. I see alot of people l just let it die and never replace it.

I live in GA and we really do not need a heater of any kind down here.. The good lord gives it to us every June-September.. Then it is mild.

My truck is ran the way that FASS wanted it to. I love the faxt that I get that stuff off the sid eof the motor which cleans it up some. I put some silicon in my WIF connector and then did the tape up and not one problem. And it has rained alot here these past couple of weeks..

I guess the main thing with doing it the FASS way is that I did not want another restriction in my fuel system. 18psi at idle and 15-16 at WOT...

Do you really thing doing the way that I'm thinking will add any restriction at all since I plan on not putting a filter in the filter housing at all?

I understand that you live in GA, but here in PA it DOES get pretty cold. Heck, we just had ice on the streets again just last week !!

I understand that the WIF sensor will probably be useless once I install the FASS, but keeping it wet I thought would also keep it happy and thus keep me code free.

Keeping it wet? I thought when it got wet is when it lit the light. Isn't that what it supposed to do?

I feel for you on the ice issue, I think that between the block heater and the grid heaters that woudl be enough but you have to make that call. I would plug it in everynight that it got down to the 30's anyways..At least that is what I did for those 2-3 weeks down here.

The housing will not make much if any diffrence on the flow rate from the FASS, it is just one of those things that when you look at it and see that it has to step down into the housing then come back out. It is all mental to me...LOL...

I am runing the 150 on mine and it flowwwwwwwwwsssssssssss!.

Gus at Farmboysdiesel or Diesel Dan at FASS will know alot more about this than I do, but from racing turbo cars over the past 18 years we try and not put to much of anything in the fuel system.

Keeping it wet I meant keeping it dipped in fuel and not water.

Yeah, I was poking around for some FASS info and I came upon this site and I saw that Dan was here and he appeared to be the head honcho behind the FASS. I figured asking here would get me the answers straight from the big cheese himself.

Be patient with Dan..He has had a ruff day.

LOL ... I hope he's not having a ruff day because he's digging through a bunch of defective systems.
