I am reverting back to the OEM LP till I get the rest of the Walbro system figured out. Question is, what's the trick to getting a positive seal with the LP to the filter housing? I had the same problem with the FASS LP emlimination piece, but I just tightened it down pretty tight and it stopped. With the OEM LP being plastic, you can only tighten it down so much before it breaks the ears. Any suggestions?

Check the o-ring and make sure it's not damaged. What things do you need to figure out on the walbro? Maybe I can help.

The o-ring that was in there was hosed. No dealer in the area stocks them either, however I did buy a o-ring kit that had the size I needed. So now all is well. I guess when I put the LP elimination piece in for the first time I must have pinched it.

What do you have left to do on the Walbro? Are you running a bypass line or bypass regulator?

I was trying an open by-pass at the CP3, but I may go with a regulator of some sort. I origionally thought I was getting super low psi at the CP3 so I removed it so I can make a trip tomorrow. However it turns out I had a bad fuel psi sending unit at the CP3, so I don't really know what I was getting. I have a post about it in the performance section, take a gander there, it should bring you up to speed on my blunder...

That's a nice install you have yourself! I just checked out your photo gallery. Is that an A1000 Aeromotive regulator?

Thanks, The regulator is an Aeromotive 13204 http://www.aeromotiveinc.com/pdetail.php?prod=20

It's adjustable to a max of 15 PSI. Aeromotive reccomended this regulator but it is not tested for use in diesel applications. They know it's being used with no reported failures. So far I have about 2k miles on this setup and have had no problems. Pressure has never gone below 14 psi.

It says it uses AN fittings, does this mean that a male AN fitting will just screw in there? The fitting kit Jegs showed looked like NPT male to AN Male.

The fittings that go into the regulator a special o-ring fittings with an an-flair on the end. these are not supplied with regulator and have to be ordered seperatly. I also had to order a plug with the o-ring because I'm only using one outlet from the regulator.(it has two) The fittings that you saw were probably AN- adaptors. If you decide to use AN- style fittings and hose you will need a AN-metric adaptor to plumb into the CP3 pump and fuel filter housing. One thing I found out the hard way was that all the inside diameters of the AN-metric adaptors are not the same. The ones I ordered from summit were to small. They were not anywhere near the opening of the normal fittings I was using. I ordered new adaptors from Rip at Source Automotive and the inside diameter was perfect.

it is a standard orb to jic adapter piece... the threads are the same between the 2 [standard national fine machine threads] but the jic [an] uses the 37* flare. the orb end uses an o-ring to seal. pretty much all hydraulic shops will have fittings like this too if you are in a pinch or don't care for the pretty colored fittings..

I wish I would of know that when I was going through the install! I had to wait for the fittings and the plug because I thought they were included with the regulator. I tried all the speed shops in the area and nobody had them.
