They work I guess
"In the end, they get fuel to where they need to go. I would recommend getting the NYLON splicers in addition to this. I found these lines irritating, they are both too short and too long in the wrong places. The when putting the fuel filter in its corresponding bracket location, the line to from the filter to the tank is too long, and the line from the filter to the front of the truck is too short. Trying to move it to compensate means the filter is out of its bracket and unsupported. The color coordination was nice, but routing them from the top of the motor, down along the firewall/trans was a bear. For the price and shipping I cant be mad, but the product can be improved."
