Air Dog 100 Hook Up

Anyone install thier AD100 to the stock fuel cannister instead of going straight to the CP3? I recently had the AD100 installed in place of my Raptor 100. The diesel shop left the lines going into the stock fuel cannister like the Raptor. Any problems w/ this? I still have my stock 7 micron filter in it, but I'm going to take it out (obvious since the AD100 has a 2 micron filter).



I would think it would not matter since both the AD100 & Raptor 100 is the gph. Except the filter is along the rail w/ the AD100 as oppose the Raptor 100 still uses the stock filter.

I installed my FASS to the stock fuel filter and left the filter in place to. I was a little nervous having a relatively long run of fuel line and no final filter.

I was wondering about that too. Are the lines the same size? I was going to get the fass 150 also.

The AD uses 1/2" lines and I believe FASS uses 3/8" line (not sure , but smaller than the AD).

I would say leave the stock filter in. It is not a restriction when it is clean, and your should stay pretty clean.

I'm not so sure that the stock fuel filter wouldn't be restrictive. A while back, I sent an e-mail to Fleetguard asking about the differences between the FS19855 and the FS19800E (7 micron replacement for the FS19855) and they sent me the full product information sheet for both filters. Those filters are rated for 59 GPH where the AD100 is 100 GPH. Because the AD has a higher working pressure than the stock lift pump, I would expect that you would get a little more than 59 GPH through the stock filter, but I think it would be less than what you get from the AD without it.

I am looking to upgrade to an AD100 in the near future too and was thinking about doing the same thing, only taking the stock filter out.

When I had the Raptor 100 it only used the stock filter (installed straight to the stock fuel filter housing). W/ the AD100, even though it uses a 2 micron filter at the AD motor location. I would think it would be similiar gph results. I'm I wrong w/ this?? I guess all that matters is what your fuel pressure is. If your stock or mild hp then I think it shouldn't matter if there is some restriction going through the stock housing w/ the AD100.

I can't say that I'm 100% correct either because I made a few assumptions that may not necessarily be true. First, I assumed that the AD100 flow rate is 100 GPH @ 16 psi on the output side of the filters (and not just the rating of the pump by itself). Second, I assumed that the flow rating of the stock filters, 60 GPH, is based on the pressure of the stock lift pump, about 6 - 7 psi I believe, because taht is the application they were designed for. I also applied a little pump operator/engineer logic (I was a volunteer with Howard Co. , MD for 10 years) in that I considered the filter a device, therefore causing a certain amount of friction loss. However, the higher pressure from the AD may overcome that. The other thing is that those data sheets I got from Fleetguard contained a whole bunch of numbers that only a mechanical engineer would understand and I may not have interpreted the data correctly (if you have Adobe Acrobat Reader, I would be happy to e-mail those data sheets to you if you're interested). So while I can't say for certain that keeping the stock filter would cause some pressure/flow loss, I can't say for certain that they wouldn't either.
