Engine/Transmission (1998.5 - 2002) Removing unused fuel filter canister

[garylmoore]

I run a Fass Titanium Lift Pump.
Today I removed the unused lift pump fuel filter canister to get to the IAT and the MAP sensor.I would like to delete this canister permanently.
The original banjo fitting is hanging unattached next to the VP44 injection pump.
The thing I do not know, is how to bypass the sensor on the side of the filter housing.
I'd like to get rid of this thing completely if possible.

If it’s just water in fuel sensor you can just unhook it and I think that you can do the same with thee fuel heater

Nothing happens if you unplug that unit and take it out.
Just remember that you loose your WIF light by doing so.

What is my WIF light?

Water In Fuel

If the filter is not in use now, you don’t have the WIF active anyway.

There are aftermarket bypass modules that make it easy, but I wouldn’t delete it or bypass it.

Many of the FASS filters aren’t better than the stock options, and many don’t use a WIF sensor or fuel heater.

Right. I just figured out WIF is water in fuel. I am using a Fass Lift Pump and it goes straight to the VP44. Nothing is hooked to the filter.

I would route your fuel lines back thru the OEM canister.

I would route your fuel lines back thru the OEM canister.

I second this, not only because of the WIF but more as a last line of defense.

I retained my OEM filter even with my AirDog... That gave me 3 filters and never worried about filtration. Always pulled the OEM filter at my change interval and they were always still white... Not worth spending money to delete IMHO...

 

[Ozymandias]

Just to mention it, the VP44 and the associated Injectors are not really picky about fuel filtration. That's good old mechanical injection stuff.
I needs a lot to make them grumpy.

Original owner around 75k added an AirDog to my 01 Sport and now at about 170k i am still on original VP. My filter housing is hanging there but not completely removed. IMHO remove it if it's in the way.

 

[garylmoore]

So, if I route the Fass to the oem filter there is no problem with it handling the flow?
I see the advantage of keeping it.
I also see the advantage of removing it and being able to see and touch things below the injectors.
I had once considered installing a bypass filter (and I would still like to do that). Most I've seen though, are installed near the engine oil filter and I can barely remove that filter as it is.
Yes, that has nothing to do with the filter canister, but it has everything to do with being able to see or touch anything below the head.
I'll decide what happens with that filter
Once the truck is running again.
Thanks for the advice... Gary

My $0.02, if your running the FASS with filters and the OE filter is already disconnected, I’d remove it. The FASS filters are good enough for me. As @Ozymandias said, the VP system isn’t as fine as the CR system that needs the extra filtration.

It completely depends on the filters being used. Some of the FASS setups didn’t even separate water. The specs on many of the filters is a joke.

If the filters are good, and a heater is added then it’s possible to remove the OEM setup… but you’re still without a WIF sensor. Most fuel these days is good and dry, but it doesn’t take much bad fuel to ruin a fuel system… and less without a warning.

I got tired of wrestling with the WIF connector on mine every time I did a filter change. Obviously not a VP44 but I left the connector dangling about 700,000 miles ago and have bought fuel all over the U.S and several Canadian provinces without any issue.

In my personal experience with over 500K miles in a CTD, I’ve never had a problem with WIF. Never once did I get a legitimate WIF light. However, I did have three different fuel filter water drain valves fail and leak a LOT of fuel quickly. I finally found a filter without the valve and used it with no issues.

I have used the Donaldson filters for quite some time and always had the drainable water filter. I never had a problem with them but there was never any water in them either. Makes me wonder how water gets in the fuel. Is it coming from the underground fuel tanks? Are you actually using a Fass lift pump? And if you are can you give me your filter numbers? Mine's a Titanium.
Just what it does happen whenever water gets into a system. Does it ruin the injectors or the piston pump? Gary

Geno's supports Fass lift pumps with several filter choices.
