Shop KLM Performance an Authorized FASS Distributor for the FASS Signature Series Adjustable Diesel Fuel Lift Pump for your 6.6L Duramax Diesel engine. These FASS Chevy and GMC Duramax Diesel Fuel Lift Pumps are the most versatile High Performance Diesel Fuel Pump on the market for the 6.6L Duramax diesel engines. The FASS fuel pumps are designed to provide your Duramax diesel engine with consistent fuel pressure and flow rates for maximum engine performance. The OEM 6.6L Duramax diesel engine does not come equipped with a lift pump from the factory. Your Duramax diesel engine relies upon the CP3 or CP4 Injection pump to act as a fuel supply pump. The injection pump has to supply itself with diesel fuel from the fuel tank. The FASS FA Series Duramax diesel engine lift pumps solve the fuel supply issues all Duramax engines have. The installation of a FASS FA C09 series lift pump on your Duramax will help to prolong the life of your fuel injection system.
These FASS Signature Series Adjustable Diesel Fuel Lift Pumps are available in the following variants to meet your engine's power level.
Keep your Duramax diesel engine running strong with a FASS Fuel Systems Adjustable High-Flow Fuel System. Choose the FASS Adjustable Fuel Pump that has the proper fuel flow and pressure to meet the exact needs of your Duramax 6.6L Diesel Engine.
Note: These FA Series pumps are a fuel pump only and must be used with your factory fuel filter. This fuel pump supply line must feed directly into the oem fuel bowl to avoid a check engine light. We recommend that you do not adjust the fuel pressure on your Duramax diesel unless you have a fuel pressure gauge installed. If you have any questions about your FASS lift pump, please contact us for more information.
The Boost Compensation Port also gives the pump consistent fuel pressure based on boost referencing from the turbo keeping fuel pressure in line with the needs of the diesel engine. You cannot make more power without supplying your Powerstroke with the correct amount of fuel. If you want your Cummins Diesel engine to make more power with increased reliability, order a FASS Fuel Pump today!
