Empty fuel tank is easy to pull out and can be done by a single person in just about 1 hour to pull down fix the gauge sender and mount again. I sat on the floor with a beer in one hand and a camera in the other and my buddy got the tank in by himself...

From a long time ago when my lift pump was dieing (Stock carter) at 8 PSI it looked like the flow of the AirDog with the starter bump (the tiny trickle). I'll see if I can produce a lower pressure and do it again... As for the the test it was gallons per hour flow rating...

Yeap... The boot is going to be big but the clamp will pull down on it... I think the 3" boot is too small... Yes you could cap the turbo and pressurize the system through that plug and test in the same fashion.

Ahhh... I thought you had a issue possibly... But thanks for the link I'll grab of copy of that and add it to the pile...

Well... I could increase the fuel pressure temporarily but using a pair of vise grips on the return line of the AirDog. Now I don't mean crimp it off completely but I mean to limit its return to increase even more fuel pressure into the VP44 for a test run say go up to 20 PSI and 25 PSI... But I think what is occuring that the internal vane pump is limiting the flow through the pump and there isn't enough volume leaking through to build to 14 PSI to open the overflow valve to flow. So in theory incresing the inlet pressure should get to a point of opening. (Only in theory)

Ok... Here is a video to show the fuel return rate for a VP44 at 17 PSI. http-~~-//www.youtube.com/watch?v=YREpPrMxkHU I love the funky green/blue color of my fuel... I heard rumors about a major pump builder planing on building a lift pump timer to keep the lift pump running after the engine is shutdown to cool the VP44. Well after doing the video I hardly doubt the idea will hold up being there is very little volume of fuel leaking though the overflow valve.

Dang that is nice... Now I got to get down to Boise, ID to buy some... Grrrr! (360 mile round trip!)

I love the comment from the guy... "Gotta pull the cab to work on anything!" At least a Dodge doesn't require that...

Thanks GuessWho wonderful and simple video showing how to resolve the minor issue! Suggestion to both though... Don't mount your AirDog leads to the battery this is where all the acid is and it ruins wiring quickly... Here is my setup... Positive connect off the stud for the alternator fuse but on the batter lead side (red). Ground hook up. Yes thats plastic but the bolt pass into the steel so far no problems. AirDog Relay and fuse together... If you look close it shares the ground screw...

No... I'm sorry I don't have one... What are you aiming to do? I'm more than willing to dig around on the internet for information for you...

Now that's rather trick looking...

Well the best I can say is pull both lines at the CAD unit and test for vacuum on both lines in both position 2WD and 4WD. As for after that the only thing I can say is to jack up the front axle (and use jackstands) and lock it into 4WD. Don't put the main trans in gear! But you should be able to tell because either the front wheel will turn free or the front driveshaft will turn with the tires.

Ohhhh... Geezz! I know exactly what that is like... I've got a wheat grinder mounted to a old butcher block and did the fresh grind flour and made bread a few times... Then what you do is back off the grinder wheel tension a bit and do a course grind kind of cracked then make that like oatmeal and eat your fresh bread and wheat oatmeal for breakfast and your ready for a great day! You might consider taking a peek at a friends site he's right up your alley... www.tractorfarmandfamily.com Your behind... 15K post at CF.com... But I hope you get home soon so you can play with your truck a bit... As for me... I love to work on the property... Got 5 acres to maintain, then take care of the irragation dam 1/4 mile behind the house. Then other day I just love to jump on the ATV and head out in the great outdoors and enjoy the scenery. This gives me a chance at doing a bit of grouse hunting, looking for new firewood areas, or maybe new ideas for just heading out to go camping...

Can you get me a picture of it by chance? --- Update I quick ran through the books and can't find anything...

Yeap the older fuel cans ran for 94 to 99 I think... After 99 then the plastic lid came into being.

Yeah you need a snubber / needle valve the grease gun hose is not enough to protect from water hammering... Even 10 feet of 1/8 air line running into my cab isn't enough... The electric sender might already be damaged..

To the injectors... As long as the ECM seeing Idle Validation switch being true the fuel rate is governor only if at idle speed above that there is ZERO fuel flow to the injectors (coast down hill). As for overflow flow if the pressure high enough to open the overflow valve then fuel will flow through there. But I still question if the vane pump internally is enough at times to open the valve when then pressure are weak?

No fair... Well at least there is good humor in the thread! I got admit though you look at where wew came from with the older 1st gen bodies that were light and didn't need a whole lot of HP/TQ to keep up with the fat boys. This is clearly evident with Taz with his 1992 Dodge (Stock injectors, HX35 turbo, VE pump turned up) when he was here in Riggins. He use to egg me on to try and pass and trust me I know I produce much more HP/TQ than he does bar none. But that old light bodied 1st Gen would flat scoot down the pavement... Never the less I can gain on him but never won a out right race... (Suckin Air and fuel pressure fell - Dropped the throttle at 98 MPH!) :banghead: "I could of had him!"

Elbow? Add a elbow to the fitting then point it back toward the firewall.

Man that just Sic! I would love to take a ride in truck like that once...

Because of the watermarking effect I added to the site i shot myself in the foot now... So I'm going to ask you guy to redo you pics for me but I'll start a new thread. http://forum.mopar1973man.com/showthread.php/2315-Pitures-of-your-truck-need-for-Video!?p=17627#post17627 Sorry to make you all start over... My Bad! :banghead:

Apparently the ABS system is still working... This is typical of when the front sensor(s) fail and come to a stop and the ABS system assumes your already locked up the nose so it blocks the brake fluid travel to prevent further skidding which it can't so full stoppage of the flow occurs till the system throws a code and lights the ABS light and then the ABS system is disabled. So to tell you the truth the safest thing you can do is just replace the 2 front sensors and the 1 rear sensor and re-enable the system.

It will automatically work with e CCD bus because the addressing system will direct the informatio where it needs to be. As for it showing correct numbers it won't for you it will be way off like showing 28-35 MPG all the time when you do your math it will be like 18-19 MPG... Reason being is the Edge and the injectors throw the tune off the computer so the data is skewed.. The only thing that is close to right would either be a Ultra Gauge or a ScanGauge II... At least those can be programmed. Found this in the TSB from Dodge... From the TSB - TAMPERING WITH VP44 FUEL PUMP ON CUMMINS DIESEL ENGINE Telltale evidence of tampering can be: a. The seizure of the pump rotor, and/or cracked or overstressed pump cam ring. b. The protective sleeve around the two wires may be rolled or cut back to gain access for connection. c. The overhead console information center (if so equipped) may read out unrealistic fuel mileage numbers (30+). d. The plastic rectangular cover and its attaching screws located on top of the fuel pump, and used to close off the fuel pump control module, may show signs of tampering and/or modification.

Go over to my Download area and download the wiring map for the 2002 and there is 4 pages of grounds listed. All mapped out for you!

Injectors??? The RV275 I got from CaJFlynn have over 400K miles on them and I'm still going... Slight miss now and then but still going strong at 20-21 MPG and good power.
