Anyone know the torque spec on the banjo bolt? I'm getting ready to do the gauge thing once I find some washers. Couldn't find it in the manual. Thanks Lads.

 

I think I found it, sorry, as you were guys. Looks like it's 17 ft/lbs.

 

I think that's too high! I recall torquing mine to 12 ft-lbs per the instructions that came with it from Geno's.

 

if you can't find some new ones, you can reuse the old ones if you anneal them with a propane torch

 

? They're rubber coated on the inside edge, how could you take a torch to these and not ruin them?

 

Assuming we are talking fuel pressure gauge banjo fittings they are 18ft-lbs according to the factory Dodge service manual and definitly don't take a torch to them. If we are talking the higher pressure banjo fittings on the fuel rail then they are higher (I think they are 20ish ft-lbs but don't remember off hand).Do however coat them with some oil or clean diesel (so they don't bind/cut/tear during tightening) and torque them. Worst that will happen is they won't seal 100% and leak a little...then you will need new ones.

 

Yes, that be the ones I was talking about. Anyone got a pic where that gauge line is supposed to mount? I'm making a bracket for mounting the isolator unit next to the battery.

 

I just drilled the lip on my battery tray ( it is a plastic/composite material so it won't rust!)and mounted the isolator to the battery tray with screws. I ran the line down and the back up to the fiting on the CP3 and secured the line in several spots to both the PS line and the wire harness. I have pics but haven'tput them in my gallery yet.

 

Thanks CRX. I'm still not exactly sure where to mount the banjo though.
How many washers are needed?

There are 2 places to mount the banjo bolt. I don't have the throttle cable mounted to the engine on mine, it is mounted under the battery tray so i had lots of room to put it on the CP3. The other location is the banjo fitting on the bottom of the fuel filter canister, I will likely relocate mine when it comes time to decide what to do about fuel pumps (likely a Walbro mod). The arrow in your picture is the one I used but in your case it may be easier to use the bottom of the filter canister

As for the washers there are 2 for every bolt, one goes on the base of the bolt to seal against the bolt to banjo fitting, the next washer goes between the banjo fitting and sealing surface (CP3 or filter canister). So if I haven't confused anyone yet...bolt, sealing washer, banjo fitting, sealing washer, CP3/fuel filter canister in that order.

I mounted my isolator to the battery tray to keep it out of the way, plus it looks nice there. There should be pics approved by admin soon in my gallery.

 

Good pics CRXsi. I'll have to study mine a bit.
Is that where most people put the boost bolt?

 

That's the same place I ID'd for my gauge. Haven't done it yet, so I'm reading with interest the experiences of those who have.

What are you all paying for the parts? I found a gauge+isolator for $122, but elsewhere a gauge for 42 and isolator for 70... but with separate shipping charges . Banjo bolts+washers are <$10.

Are/did you guys use a snubber (eg needle valve)? How much, from where?

thanx. sorry to pester, I hate over spending.

 

As for the boost bolt, you can use any one of the intake manifold bolts that are next to the valve cover. I do have a slight buzz from my boost gauge at higher boost levels...one of the fixes I am told is to relocate the boost bolt to a location closer to the front of the motor so I would be tempted to start with a bolt closer to the front.

As for a place to purchase, I had extremely good experience with Dave at DieselManor. His prices were good as well.

 

ok, i didn't realize they were bonded washers.. if they are plain copper washers you can do the torch trick.. rubber and flame don't mix..
