Product Description
AIRDOG A7SPBC258 II-5G DF-100-5G is a 100 GPH frame-mounted air/fuel separation lift pump engineered for 1992–2000 GM 6.5L (Detroit Diesel) trucks. It removes entrained air, vapor, water, and particulates before fuel reaches the injection pump, stabilizing fuel pressure under load, improving throttle response, and protecting injectors for longer service life.

FAQs
Will this replace my factory lift pump on a 6.5L?
 Yes—this kit is designed to replace the weak factory low-pressure pump and provide a steady, filtered fuel supply to the injection pump.
Do I need custom tuning after installing the A7SPBC258?
 No tuning is required on stock 6.5L trucks; it simply improves fuel supply and filtration. (Custom builds may choose to retune.)
How often should I service the filters?
 Follow AirDog’s recommended intervals based on fuel quality and usage. Inspect more frequently if you tow or drive in dusty/dirty conditions.
Is 100 GPH enough for my setup?
 For stock to lightly modified 6.5L applications, 100 GPH is ideal. If you plan significant fueling upgrades, consider the DF-165-5G listed above.
