This is a bolt in replacement billet aluminum housing High Pressure Oil Pump for the 2003-2004 6.0L Powerstroke engines. There are HEAVY DUTY upgrades to the internals in addition to the billet housing.
There are two versions:
STOCK OUTPUT: The stock output Heavy Duty version has all the same upgrades as the high output version in regards to durability. This option is for stock injectors up through 190cc. It is a perfect option for those not looking for High performance parts as the longevity - in theory - might prove better on these units as one would presume. Our "Stock Output" is slightly larger in volume than a stock pump.
Have you recently lost your 03-04 HPOP? When they fail, they usually give you no signs or advance notice, they just stall out the engine and it won't re-start.
There are several reasons for this in the stock pumps. We have addressed all of these OEM issues in the design of our heavy duty pumps - both versions.
THIS IS A FAIRLY COMPLICATED INSTALL FOR THE DO IT YOURSELFER. IF YOU ARE NOT FAMILIAR WITH THE PROCEDURE, LOCATION OF YOUR PUMP OR SCANNING METHODS THEN THIS MAY NOT BE THE MOD FOR YOU. THERE ARE NO INSTRUCTIONS PROVIDED FOR THE 6.0L INSTALL.
