Airdog II-5G 165 GPH Air Fuel Separation Lift Pump 98.5-04.5 Dodge 5.9L Cummins W/In-Tank PumpThe 98. 5 02 2nd Gen Cummins got a pretty bad rap over the years for failed VP44 injection pumps, many claiming it was one of the worst decisions ever made to mate this supposed failure prone pump on a Cummins powered Ram.

The 98.5-02 2nd Gen Cummins got a pretty bad rap over the years for failed VP44 injection pumps, many claiming it was one of the worst decisions ever made to mate this supposed failure prone pump on a Cummins powered Ram. Now, was it really the VP44's fault, or was the engine bay mounted lift pump really the culprit? In most cases, the failure of the low output lift pump causes the demise of the injection pump. And to make matters worse, they continued to use a similar lift pump placement all the way through the 2004.5 model years before going to a higher output in-tank lift pump. So how do you really fix one of these trucks for good? Easy, ditch the in tank stock lift pump and upgrade to an AirDog!
The AirDog II-5G is an all in one premium fuel pump and filtration system for your 1998.5-2004.5 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 DF-165 systems feature a built in adjustable diaphragm pressure regulator. All AirDog II-5G systems include a complete installation kit. The AirDog II-5G, for this particular application, is preset at 17 psi from the factory for a stock application. The regulator is adjustable up to 55 PSI so you can fine tune the system to perfectly match up to your current and future performance upgrades.
HOW IT WORKS:
The AirDog II-5G DF-165 draws fuel from the fuel tank through a 1/2” 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 Gearotor 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.IMPORTANT INFORMATION REGARDING IN-TANK FUEL PUMP:
This specific AirDog unit is designed for trucks featuring the in-tank
lift pump. For those unaware, all of the 1998.5-2004.5 Cummins powered
Rams came from the factory with a block mounted lift pump. However, if
it ever failed and had it replaced previously, it very likely was
retrofitted to the newer design that actually placed the pump in the
fuel tank. If you're not sure where your pump is located, simply "bump"
the key, which will engage the pump, then listen whether the hum from
the pump is coming from the engine compartment or the fuel tank.

Romance with a side of Thrill
Format: Kindle
4.25 stars!
I was immediately engrossed in this debut novel, with the thrilling beginning and obvious future romance between Lou and Ava. I thought the setting of the town was wonderful, full of small charm and supportive characters. The little nods towards the continuing threat to Ava’s life were good. The budding romance was great, too! I think the intimacy scenes were soft and perfect.
The main reason this didn’t reach 4.5 stars for me (thus would’ve rounded it to 5 instead of down to 4), is because of the POV switches during chapters. They’re a bit jumbled in; the reader is suddenly seeing or hearing things from Lou when it started with Ava, but then it quickly switches back to Ava. It’s not my favorite way for a story to be shared.
I also lost a little steam towards the middle-end, right before the big finale. I’m not sure if my other hobby distracted me or if the story hit a slow spot. It’s possible I was hoping for a little more excitement. This story had more romance than thrill.

Blood and Muscle
Format: Kindle
I had this on my shelf for a while. lG reviews were great, the cover was pretty, and it sounded really interesting.
It was better than I expected! Love when that happens🥰
The story was great, the writing was good, and the characters were amazing! Ava and Lou's chemistry at first was a little charged. But as the story went and their relationship developed, it turned into something more tender and very intimate. Throw in the witness protection thing, and you have quite exciting romance. I will be reading this again!

Thrilling Fusion of Suspense and Sapphic Longing: Blood and Muscle Delivers with Depth and Desire
Format: Kindle
Elle Alexandra delivers a masterfully woven tale of suspense and romance in Blood and Muscle, a novel that seamlessly balances pulse-pounding tension with deeply felt emotional intimacy. Set against the stark yet breathtaking backdrop of Cedar Falls, Wyoming, this story immerses readers in a world where danger and desire are inextricably linked, and where trust is both a luxury and a necessity.
At the heart of the novel are Ava Bedford, a reluctant fugitive thrust into witness protection after witnessing a murder tied to a powerful political figure, and Sheriff Lou Harman, a woman whose life is defined by structure, solitude, and an unwavering sense of duty. Their dynamic is as compelling as it is electrifying, Ava’s sharp wit and warmth slowly chipping away at Lou’s carefully maintained defenses, creating a relationship that simmers with slow-burning intensity.
Alexandra’s character work is nothing short of exquisite. Both Ava and Lou are richly developed, imbued with layers of vulnerability, resilience, and undeniable magnetism. Their interactions feel organic, their chemistry electric, and their individual arcs deeply satisfying. The town of Cedar Falls, too, becomes more than just a setting, it breathes with its own quiet menace and rugged charm, a place of both refuge and lurking danger.
The novel’s pacing is expertly handled, with the tension mounting in a way that keeps readers perpetually on edge. Alexandra deftly balances moments of tender introspection with sequences of gripping suspense, ensuring that neither the romance nor the thriller elements overshadow the other. The prose is fluid, evocative, and often poetic, drawing readers deeper into the world she has so carefully crafted.
If there is one minor drawback, it is the at-times subtle transition between the protagonists’ perspectives. While both Ava and Lou’s voices are distinct, a more clearly delineated shift in POV would have further enhanced the reading experience, offering even greater immersion into their respective inner worlds. However, this is a small quibble in an otherwise exceptional novel.
Blood and Muscle is a triumph, an intoxicating blend of romance, intrigue, and raw emotion. It is a testament to the power of resilience, the fragility of trust, and the courage it takes to love in the face of uncertainty. Elle Alexandra has crafted a story that lingers long after the final page, making this a must-read for fans of sapphic fiction who crave both heart-pounding suspense and soul-stirring romance.

Ava witnesses a murder of a congressman and is forced into witness protection and relocated to Cedar falls. This is where she meets sheriff Lou. Chapter 1 had me quickly drawn in as it starts with Ava witnessing the murder after her shift. The tension was palpable. The writing was perfect.
I really enjoyed this book. The crime/mystery along with the romance made the story intriguing. Lou and Ava slowly start to develop a beautiful relationship with undeniable chemistry. There is just enough angst that had me stuck wanting to know how the book was going to end. Towards the middle of the book we get Lou’s backstory which pulled at my heartstrings. She went through so much as a child which explained why she was so closed off as an adult. The spice was sweet and well written. This book gave me all the feels. It’s fun, mysterious, intense, emotional and hot. I feel so much happened in 300 pages and I still craved more. The ending was wrapped up perfectly with a HEA. Lastly, I was so happy to see chapters titles! Seems to be a rare occurrence these days.
