When I installed my GDP 2-micron filter and big line kit I didn't use anything on the threads of the fittings. I did use the provided Cummins seal washers at the CP3 and stock filter housing. Well, I think I have a slight leak at the input line/filter head fitting. It looks like it may be where the large adapter fitting threads into the filter head. Those adapters at the filter head are as tight as I can get them. Should I have used teflon tape or some other thread sealer on the fittings? I did'nt want to chance anything getting into the CP3.

 

I would use teflon tape or teflon paste. Just be very careful with keeping the paste away from the passageways.

I second MikeyB. I had the exact same problem. Used a combination of teflon sealant and teflon tape, very anally to avoid any contamination. Sealed like a dream. I called Richard on it just to be sure, and it seemed like an obvious answer.....kinda should be included in the instructions. Even though they are pipe threads, they are so tight you cannot get more than 3-5 turns out of them without using a 2' long wrench or pole on the end of a smaller wrench.

 

Thanks guys. I spoke to Richard myself and he suggested the same. Thanks again!

 

PTGarcia,
So how hard was it to install? How long did it take you to do, and what level of mechanic are you? Is it something I could do, I mean I installed my exhaust, air intake, chip, etc?

 

Also, I would put teflon tape on it for sure, I dont know about paste, but I dont go without tape on pipe fittings!

 

It's really pretty easy. I'm a decent mechanic, but I'm lazy and don't like to do my own stuff. But I did this and my Quad box myself.

Anyway, I probably have 2-1/2 hours total time in it, and I work pretty slow (I can never seem to get organized when wrenching on things). The hardest part is probably connecting the fittings to the underside of the stock filter canister. I had to access them from the wheel well, and with the big 325's stuffed in there there's not much room for my fat body! And definately use tape. Richard is going to update his instructions to point that out. Other than that its pretty easy.

Oh, I definately recommend using the listed size drill bit for the mounting ear. Its kind of an odd size so make sure you have one before taking everything apart. I used a slightly smaller bit and it made tapping the hole with the supplied self-tapping bolt a be-yotch.

 

I didn't use any tape when I installed my 392 Comp kit the other day, and I didn't see any leaks after my quick testdrive but I'm going to keep checking just to make sure. I cranked down pretty good on all the fittings though.

I will be ordering the MK2+ Big Line kit sometime in the near future to compliment the new pump

 

What exactly is the advantage of the big line kit?
Does it get more fuel to the cp3 than the stock line with a 392?

 

ptgarcia,
Where did you mount the filter?

MikeyB

 

Under the intake horn per the instructions. It fits perfectly.

 

It will deliver a larger volume of fuel to the CP3.

 

Bummer. My APPS is in the way. Will have to find a spot to mount the kit.

MikeyB

 

I mounted mine on the front left hand body mount, easily accessed, and out of harms way for the most part.

Here is with the fender liner removed. The massive CAT filter was dead even with the bottom of the bumper and fender liner. I now have the Fleetguard filter on there that is about half the size.

 

Excellent! Thanks!
