Feed The Beast - Fittings Kit - 6.2L/6.5L - Free shipping!
When you first see how small the diameter of the inlet to the injector pump is on a GM 6.5L diesel, it is laughable. “How can so small a fuel line deliver enough fuel to move this fat pig,?” was my first thought.
At Walking J Designs, we’ve partnered with the inventor himself, who first came up with the idea of enlarging the fuel line from the fuel manager to the injector pump. These large and powerful vehicles come stock with 1/4" fuel line restricting fuel to the injector pump.
This modification prevents fuel starvation among modified and heavy towing 6.2/6.5 GM diesels. Increasing fuel flow has also proven to slow the demise of the poorly placed PMD. (Although, you still should really remove the PMD via a Heath type kit.)
This simple kit of parts includes the fittings required to more than double the available flow and very simple instructions for you or your machinist to modify the existing fuel manager.
The fitting on the left is the stock fitting. Can you believe the GM engineers thought you could climb while towing? The fitting on the right is our custom machined Walking J Designs fitting.
Fittings are warrantied for 2 years.
