hey guys, i have an airdog 2 150 gph pump on my truck.

 

yesterday when driving my fuel pressure all of a sudden hit 0 and i continued to drive home because it wasnt acting funny. when i shut it off and turned key back to run position, the pump wont kick on. ive tried everything i can think of. i traced the ground and hot wires as good as i could without a test light. i made sure they had good clean connection. (dropped my test light on the walk from the building to the truck and broke it of course)

 

i couldnt test the relays, and dont even know where to begin and what to begin looking at because i did not hook this pump up. i dont know which relays or fuses or whatever the pump connects through, anything like that.

 

i am showing error codes P PCU, P0500, P0462, and P1693. all unrelated id assume.

 

can someone please explain to me how to figure out if that pump is burnt out or not. if it is i need it replaced like 3 hours ago. college is starting back, i cant get to work, im at a loss for ideas. anyone that can take the time to help me, i can pay you some money for the time

 

thanks guys,

Allowing too much current to flow through could end up melting the wires that supply power to the pump. If it keeps burning out the fuse rated for it there is either a short somewhere in wiring, or the motor on the pump is bad.

Double check your ground to make sure it's tight and corrosion free. If it pops the fuse again I would pull the round cover off and have a look at the gears to make sure nothing is caught in there, though I'm pretty sure it would pop right away again if there was. The motor is easy to pull, 4 long screws and it's off. If the pump is not warrantied I would pull the motor just to have a look and make sure nothing is out of place. Could be something as simple as a cheap seal allowing fuel past the shaft. Worst case scenario they do sell motors individually so you will not have to replace the entire pump.

could i just swap the fuse for a 30 amp or so?

Should never increase fuse size to over come a problem this will result most likely either in melted wires or a possible vehicle fire. If the fuse is blowing out there must be something causing a over-current condition. Pinched wires to ground, locked rotor in the fuel pump, internal issues to the pump motor. Etc.

 

Should always use the same size fuse or smaller. This way you never end up with a vehicle fire or mess of melted wires.

yea that probably wasnt the best question haha

 

i swapped it for a 20 amp fuse. i hope it was just a random occurrence and i dont need a new pump motor. they quoted me $219.00 for a new one.. 

so could it just be a 1 time occurrence of it blowing the fuse? im going to drive it until it decides to let go again.

 

anyone thats had this problem, how long did it take for the fuse to blow again after the first time? 

 

 

If the fuel has gotten into the pump I would imagine the fuse would probably blow almost right after you turn the key on. If there was some debris in there it may be able to pass through the pump before it pops the fuse again.

 

 

When I bought my AD, I got this less than desirable design spoken of. About 6-9 months in after install, it happened to me. Fuse blew and blew a fuse everytime I tried to replace it. Took 2 fuses to figure out something was really wrong. Towed it home and called AD. Bad motor! They sent over a new one free of charge since I had warranty. Took the old one apart and the seal to the motor was non-existant. Diesel in it everywhere...

hey all,   did  AD  ever  admit/confess  to the  batch of   poor  motors?   (they alone  should know of  exact  serial number  of  where it  went south!)  And of course,   when  they   'fixed' it.     (they DID  fix it didn't they?)

 

Ltk,  you said  you swapped  in  a higher fuse.... so    DID IT WORK???

i took the higher fuse out and put a 20 back in, and the pump is still kicking on like normal when turning the key. hasnt block yet. knock on wood!

I sent in  my warranty card. When mine was leaking everywhere, they told me it was registered to someone named Brian. I had to all Thoroughbred & have them Email the recipt. Took a week to get my replaement & it has wildly varying pressures. They cannot & will not send out noties if the database is all wrong. Such a joke....

maybe i should just not go with airdog if this is how they do things?

For the price of a motor compared to another pump of similar capabilities I would personally stick with what you got. It would be interesting to know the percentage of pumps that actually did fail early. We always hear of the ones that do but how many are there out there giving years of trouble free service that you don't hear about...The majority (not all) of the failures were the lower end Raptor pumps. I had one of them as well for some time, started leaking fuel internally, and it was replaced no questions asked. They did not require that I send in the old pump and had a new one on my doorstep within 3 - 4 days. My experience with their customer service has been positive. If you choose to go that route filling the warranty card out and sending it in promptly is very important.

my pumps been on the truck since like 2006

 

but ive only owned it since early 2012, so not sure if this is a replacement or original. after driving around all day, so far so good still..

6 years isn't too bad for a motor that runs non stop while the trucks is running, depending on the mileage it's seen in that time frame.

Ive done 20+ pumps and have only had to warranty 2. No questions asked I had new pumps in 3 days. If I didnt trust them, I wouldnt have installed a airdog2-165 on my personal pickup.

I love my airdog pump!

Soon, there will be a better option. A few months & you will see how pumps & filtration should be done.

No Chinese junk & Industry standard parts.

He's not joking either... I know what he's talking about too... I might be lucky to be included in the design process too.

Sure, but at a $800+ price tag...could almost replace a VP for the price.

Exactly what diesel4life said.

It may be in that range, but not be failure prone. It will start with the Liberty module, 10 Mic ABSOLUTE centrifugal filtering/aquablock/water seperation, WIF & heater in the 1st filter, pump, then 3 Micron ABSOLUTE filtering with aquablock, all hoses, harnesses & fittings. Also, it will have a true rating, not one that states a flow that the filters could never handle. Yes, it will be pricey, but premium. You will not be getting towed home because of cutting corners You won't be replacing the pump every 6 months to a year & hurting the VP each time.

It will be desireable to some & not to others. It will be speced out to truly handle any HP rating that a stock VP44 pump can handle.
