2004.5 - 2007 GM Duramax LLY/LBZ

Includes hoses, adapters, fittings, pick-up - everything needed to do a complete installation.

The stock GM Duramax fuel pickup line is 0.240” I.D. while all the fuel line and connectors are 0.500” I.D. As a result of this restriction in the fuel tank the pump has to work harder in order to retrieve the fuel thereby starving the engine of usable power and also potentially impacting Injection Timing as a result of cavitation.

TTS has developed a fuel pickup system upgrade for the GM Duramax where the fuel pickup line is 0.500” I.D. Made of 6061 billet aluminum that replaces the stock plastic restrictive pickup, and machined to accept a 5/8 hose to increase the fuel flow by over 140%.

* Tests have shown that 7”Hg is not uncommon in a Duramax powered vehicle using a lift pump as measured at the top of the sending unit, this can be lowered to 1.5”Hg using our Billet Fuel Pickup
* Designed and manufactured using the latest in solid modeling and Cad/Cam technology.
