The Pureflow AirDog FP-100 4G A4SPBD136 lift pump, or Fuel Preporator, is a must have upgrade for your 1989 – 1993 Duramax. The fuel system on your diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (preset at 10 psi) Duramax lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The suction/fuel supply side connects directly up to the factory suction line on the frame rail. The pressure side connects to the factory injection feed line bypassing the stock frame mounted low pressure pump.
DESCRIPTION: The 4G fuel pump features a fully adjustable integrated diaphragm pressure regulator. This regulator offers more consistent fuel pressure and allows for higher flow rates at pressure. It can also be boost compensated to battle any pressure drops under open throttle (boost compensation kits sold separately). The AirDog 4G also includes an updated 12 gauge wiring harness with Metri-Pack 280 connectors, which allows for higher current flow without creating excessive heat.
The AirDog FP-100 4G Duramax A4SPBD136 lift pump will solve infamous P0087 & P1093 low fuel rail pressure codes. This positive supply being fed to your injection pump will also add performance, throttle response, and longevity to your vehicle. Due to extra stress on your fuel system from either high mileage and/or additional performance modifications, like a tuner or larger injectors, your injection pump can become weak over time. This may result in a drop of performance, reliability, and fuel economy. The supplied water separator (WS100) and fuel filter (FF100-2) mount to the pump. They filter your fuel down to a 2 micron rating which surpasses the stock fuel filters filtration capability.
This AirDog FP-100 4G Duramax A4SPBD136 lift pump is recommended for trucks that have a stock to aggressively upgraded fuel system. Therefore meaning stock to larger injectors and injection pump; will also support aggressive tuning. Perfect fit for daily drivers to performance applications reaching up to 1,000 RWHP! Backed by a lifetime warranty.
AIRDOG’S GUARANTEE The AirDog FP-100 4G for the 15-16 Duramax is engineered with the most proven, quiet and reliable motor technology on the market. It also retains the “demand flow” capabilties of the previous AirDog systems. This means that is has a constant supply of clean, pure fuel available for your injector pump at all times. Any fuel not used by the engine is simply recycled back to the tank, so it will never “over-fuel” your system. The FP-100 4G A4SPBD136 uses the same better-than-OEM fuel filter (FF100-2) and water separator (WS100) as the previous AirDog models. Pureflow AirDog products are manufactured in Shelbyville, Indiana. Finally, built by a team of skilled workers with unsurpassed attention to detail and using the most stringent quality assurance.
Looks like I get to be the first review for these guys. Let me start out by saying that I have had 3 other cars of a similar caliber to my GTR serviced/worked on and upgrades installed at other shops and none took the pride and level of detail that these guys did. I wish I could see all the welds on the downpipes and exhaust because it looked like artwork. Their fabricator made sure to send me daily updates and pictures which was also a big deal to me. For being an out of state experience it made it seem more like they were local to me and that I had known them for longer.

Took the leap of faith on buying a set of their R35 intakes and downpipes because the price was half of anyone elses plus their car hauls a** at the track. Install went smooth and the power seems to be even better than advertised. Cant wait to get tuned in a few weeks. Their shelf tune honestly has to be 600+ hp as I pulled on a Hellcat last night. I see these guys and gals going a long ways if they can get out there and advertise. Customer service is on point paired with BIGGG savings for the winning combo.

Bought a Motec and had these guys build the harness and set it up fully. Track car that received the level of attention and detail of a show car while here. Made me feel at home every time I popped in for a visit and always offered to buy me lunch/dinner. I don’t see me shopping anywhere else as they make you feel like your family.
