Fuel Cooler Line included

Not Included in Set: Hoses between fuel line and fuel tank 5070-01D and Cooler Connector Lines FL591-A2D or SS591-A2D. These parts are available for purchase separately

Please Note: If you have purchased an aftermarket replacement fuel cooler, the fuel cooler connector lines attached to the fuel cooler may be different than the OEM fuel cooler connector lines. As shown under images - in Illustration A, the aftermarket fuel cooler connector lines are made with a straight sharp edge. When these are plugged into the fuel cooler line, they will cut the o-ring inside the connector causing a leak. If you wish to replace the fuel cooler connector lines before installation of the fuel cooler line, they are available to purchase under part number FL591-A as shown in Illustration B

We are unable to warranty any of our products that are damaged by aftermarket fuel cooler connector lines.

High quality, like the color

"High quality, like the color method used to ID where things go however very difficult to get in correct locations. Wish more pictures were available showing pipe relationships to GMC frame connectors. The flexible lines are very stiff (inside tube gets pinched), so need to get others made, to accomplish the tight turns. Would not go with stainless because in some areas more of a bend needs to be made."
