Airdog II-5G Air Fuel Separation Lift Pump System 89-93 Dodge 5.9L 12 Valve CumminsFrom the factory, 1st Gen 12 Valve Cummins have a mechanical lift pump that actually works pretty good at maintaining adequate fuel pressure to the VE injection pump at stock and slightly above stock power levels. That said, its almost TOO easy to add power to a 12 valve through pump and injector upgrades, which now tasks this stock pump, not allowing for the full power potential of the performance upgrades you're making.

From the factory, 1st Gen 12 Valve Cummins have a mechanical lift pump that actually works pretty good at maintaining adequate fuel pressure to the VE injection pump at stock and slightly above stock power levels. That said, its almost TOO easy to add power to a 12 valve through pump and injector upgrades, which now tasks this stock pump, not allowing for the full power potential of the performance upgrades you're making.
The AirDog II-5G is an all in one premium fuel pump and filtration system for your 12 Valve Cummins diesel. This system removes water, particulates, and entrained air from the diesel fuel. The entrained air that is separated from the fuel is returned to the tank through a small return fitting. The fuel is delivered to the engine at the correct pressure and flow rate to meet the demands of the engine under all operating conditions.
The AirDogII-5G systems feature a built in adjustible diaphragm pressure regulator. All AirDog II-5G systems include a complete installation kit. The regulator allows for more fuel pressure adjustability, better fuel flow at pressure, and can be boost compensated.
HOW IT WORKS:
The AirDog II-5G draws fuel from the fuel tank through a 1/2” suction line and the DF-220 draws fuel through a 5/8” suction line to reduce the risk of cavitation at the pump. The fuel is then drawn through the water separator where 92% of water is removed per SAE spec 1488. It is then pressurized through a Gerotor pump and sent to the 2 micron fuel filter before it is sent to the injection pump. The air from aerated fuel, due to tank sloshing and engine return lines, is separated and sent back to the tank through the 3/8” return fitting. The excess fuel that the engine does not use is recirculated through the diaphragm regulator back to the suction side of the pump.

Still working great!!
I really didn't have a good feeling about ordering a starter online, but I was in a situation where I didn't have the time to get to the auto shop before my day off and Amazon could get me this part just in time. So I reluctantly gave it a shot.
When it showed up it had a couple of small black pieces of plastic loose in the box similar to the pieces shown in another review on here. It didn't look like they from anything functional. I really needed to get my wife's car running so decided to install it anyways.
The install was easy and it was a perfect fit. The only draw back would be that the signal wire didn't click in place like the signal wire on the original starter. But it was a snug fit.
It has been installed and working great for a month now. Very happy with my purchase.
It also had a message from the seller when I opened the box giving the starter a 2 year warranty. Very cool.
If the starters fails in the next two years I'll get on here and edit my review. So if your reading this then it is still working great.

Great quality at a great price too!
Husband got this for his ‘05 Camry and says it looks and fits just like the original. He was happy that it simply slid in with no adjustments needed. It’s been a couple months now and no problems at all. Very satisfied with this item.

Electrically good. Fitment not so good.
This starter worked fine when installed. The only reason I didn't give it a 5 star rating was fitment. the hole in the bell housing is slightly larger than the starter. The old starter, OEM, was a right fit. This puts all of the strain and torque of starting the engine on the two bolts that hold the starter in. I expect this to fail at some, hopefully, distant point in the car's future. In order to retorque the starter bolts, the battery and airbox have to be removed.
