Engine/Transmission (1998.5 - 2002) secondary fuel filter

[RCrosby]

hey guys, looking at installing a second fuel filter, second time in 6 months got some water in fuel, i use baldwin fuel filter in stock filter housing. l/p is near tank, with 1/2"lines all the way, fuel psi is 16-14 psi. what you guys are using for a secondary fuel filter. and what is the micron on stock fuel filters. thanks

Try Glacier Diesel Power at www.glacierdieselpower.com Nice setup.

You beat me to it! I have Glaciers 20 micron filter/water separator before the LP and their 2 micron after. all down on the frame being fed by Vulcans big lines/fittings.

The whole system has so much volume now. . it acts like an accumulator. It's hard to see an fluctuations in pressure no matter what you do with the go pedal.

So far I'm pretty happy with the set-up. I want to see how it work when the weather turns cold. Those filters are exsposed to... well everything that the under part of the pick-up is exposed to; cold, wind, ice, mud, rocks etc. .

I keeping spare everything when I travel these days.

ALL fed by the little plastic 90* fittings on the fuel cannister?

So does GDP make a mounting bracket for the 2nd generations? All I see on their website is mounting for a 3rd generation? Are you just taking the third generation bracket and drilling your frame for mounting? I would like to keep my OEM filter and place this new 2 micron between the factory filter and the VP44 pump. If I mount on the frame this will make me drop in elevation from the OEM filter down to the frame which will result in a high point for air to accumulate. I quess I can install an air bleed valve in the hose between the two filters. I also have a vulcan kit with the OEM lift pump on the frame and run 14 psi at idle, measured at the VP44 inlet. Do you know what the increase in pressure loss is with the new 2 micro filter?

Did you have to tell me that? What are they by the way... 1/4" ID?

The mounting brackets are universal in that they're not really made for any one model or make of truck. I just put them where they would go and drilled some holes.

I don't know what the pressure drop is across the 2 micron filter as I did the whole install at once. My LP alone (without the in-tank pump running) will put out about 12psi to 14psi depending on fuel temperature. Cold fuel is one of the things I'm concerned about. I bought a 10 micron replacement in case the 2 micron pulls the pressure down too much.

I think I am going to install a bypass around the 2 micro filter with valving so when it is cold we can bypass until the truck warms up. I would really like to find a location near the engine block so it gets some heat. Since we have removed the factory lift pumps do you think we could mount it there?

I would not mount it in place of the old lp, fuel filter would act as a great heat sink and heat all that fuel nicely, ok in winter, not so good in summer

Yeah. . a guy's got to take into account his location and winter temps. We usually head south in the winter so I wasn't TOOO concerned with these filters under the trcuk.

If I spent a lot of time in a really cold climate. . I'ed go with heated filters. By the time we get back to Idaho in the spring the brutal cold is over but you can still see temps in the high teens.

I'll just have to see how pressures hold up. I'm sure I'll get over 5psi. . and that's all I ever had with the in-tank pimp alone.

I used two Glacier Diesel Power (GDP) fuel filter heads screwed together with the 20 micron fuel/water seperator 1st and the 2 micron next. With the supplied GDP brackets combined with a fabricated aluminum bracket to strengthen the setup, hung the whole thing under the airhorn.



I also used the GDP "Fuel canister eliminator manifold" and did away with the stock filter entirely. The 20 micron fuel/water seperator is in front and the 2 micron filter in the back. Changing the fuel filter(s) is quick and easy.



I have a lift pump fuel pressure guage (and rail pressure). I have the stock fuel tank and a 40 gallon in-bed auxillary tank from American Tank, Frisco, Texas.



With the above setup, my stock lift pump runs 8-9 psi and I can pull it down to 5 psi. The lift pump in the auxillary tank runs 15-16 psi and I can pull it down to about 10 psi.



Mike Shuman (American Tank) is fabricating a plate to modify the stock tank to remove the stock lift pump, float, etc. , to accept the lift pump he uses on his auxillary tanks. So, in the end, I will have a 2 tank, 2 lift pump fuel system, switched by a 4-way valve running through the same filtration system.
