"OFFICIAL" What did you do to your D-Max today?

[DMAXchris]

Could the alternator be sending too much voltage to the pump? When the engine is running 14V is sent to the batteries.

Thats how Airdog instructs you to hook it up. My cousin has it wired the same way on his LBZ and hes had the same pump since 2010. The only difference in our trucks is his has the PPE pickup in it, and mine is factory. My pump is always louder than his. Its a high pitched whine that you can hear in cab with the truck running.

Yea I just realized how retarded I sounded lmao. Mine is tied into the battery term. It's getting more than 12v also. (Douh) :banghead:

Power is direct from the alternator. Key on is the normal stacked fuse. Ground is to the frame. Seems like I get 2 years and its done. I even kept the pressure way down on this one to make sure that wasnt wearing them out early.

Huh?

It's been 4+ years now, but I remember key on and power being pulled from the stacked fuse, I didnt or rather, don't remember running a separate power wire, and in fact, I pull the stacked fuse when I switch tunes to cut power to the pump...

Not trying to be condescending or a dick, but are you positive that it's hooked up properly?
Also, when its cold your alternator is working triple time, maybe it's not feeding a solid enough state of energy to the pumps motor?

 

[motoking_1990]

Idk how the air dog is but mine has a thicker power wire. And another wire the turns the pump on with the key on a stacked fuse.

Im positive Jason. You had to have ran another power wire for constant. The key on fuse jumper only provides voltage to power the pump up when you have the key in "run."

How much pressure do you run? Mine wines pretty good if I go above 13-14psi.

I set this one at 10psi and never touched it again. My last one I ran at 16 and it was annoying. You could hear it at 65 mph!

Lol
I had to check...I do have the main power lead for my AD pulled from the alternator
Ha, I'm an idiot
But you guys knew that ready...
Nuthin's changed

Truck develop a throttle and speed related noise at 65 and 6th.. I've checked everything I can..including wheel bearings Can't find culprit... Seams I'm going to have blow it up to find the failing item... Hate doing it this way
Hopefully I can get everything picked up and kicked off
Have I mentioned how much I hate trouble shooting problems like this!
Fwiw taking us52/18 from Rochester MN to Janesville wi

Found idler arm bracket and arm are sloppy which killing my tire.. So new part tomorrow then hopefully off to Laredo tx for Monday kickoff

Gues 276k on original steering system time for new stuff

Replaced idler arm and brakcket, new tire and new transmission mount.. All needed replacing but not the issue causing the noise
all fluids checked greased
Heading for lerado tx early AM, 1500 miles then ~300 back to Houston to kick of stop #2
Hate having something wrong and I can't find it :banghead:

Get the dodge spring kit, I run mine at 20 psi with no added noise, ran it maxed out with the dodge spring on my LMM, if fact I think it got more quiet turned way up. Why run it at 10 psi if you can run more? It's only lilys and lb7's that freak out over pressure. I've only had 1 LMM freak out with a maxed out pump and I only turned that one down a half turn and it was happy. It's not usually the pump making the noise by the way, it's the jam nut on the regulator spring.

Replaced my radiator and got the old girl back on the road. I hated having to drive the company camry every day. Especially with the weather were having this weekend I'm glad she's back going.
Tomorrow I'm helping a buddy install a leveling kit and new shocks on his dmax

I actually get high rp codes if I run mine at 15. Weird.

I put an in-line pressure gauge on my feed line, as close to the CP3 as I couod get, to KNOW what was going on with my lift pump pressure

If I run my AD165 above 12psi, my LBZ lopes pretty bad
8psi and under it will drop to nearly zero psi under WOT on the big tune

I've got it adjusted to where the needle bounces between 10-11+psi @ idle and it works out well...that for a stock CP3, 60 over, single turbo, stock engine- setup

 

[Harbin_22]

10psi on mine was enough to support 2700us on 120% and maintain 28k rp. I don't see a need to go higher on psi if it is holding RP

Changed the oil, fuel filter, trans filter, rotated tires.

I just used the test port to check them, not sure why I didn't have issues turning them up. Maybe it's in the tuning, the cummins cp3 regulator s the same right?

727,150 - Front axle pinion seal and left axle seal replaced
727,165 - windshield replaced.

Pulled the front end apart so all the broken stuff could fall out and ordered parts. And looked at it and my garage in disbelief of all the salt and mud. Truck will be fixed tomorrow and my garage floor is getting scrubbed to death.

 

[kiwilml]

Finally decided time to fix my small fuel leak on back of cp3. Find out the fuel supply fitting that screws into back of pump had to long of threads and bottomed out before was fully tightened up.

Forgot to take a pic of the difference in my new fitting and the old one. It must have been really close to working though because I'd ran it about a year and it just started leaking a month ago or so.

If anybody got a kit from Wcfab a year or more ago you may need to be prepared to do this, I don't know...


(And for some reason I can't post a pic now, says to large.. Why is that?)
