Nylon Installation Instructions:

Step 1

Cut the new nylon hose in the same position as the original nylon hose.

Step 2

Cut the original nylon hose in the same position as the new nylon hose.

Step 3

Use the original nylon hose with connector and attach it with supplied union to the new nylon hose.

They carry fuel and dont

"They carry fuel and dont leak. my mechanic did the installation, I only ordered and supplied them since they don't order online parts. From gm the lines would be one piece and more pricey. Although I did end up buying the 3 rear nylon lines through the dealer, another $200 +/-"

Could have used the retainers

"Could have used the retainers with the lines. Only 1 line had them. The lines fit as promised. I would never attempt this again. The process is an absolute nightmare. Getting at the top lines involved removing the front driveshaft. You can barely get at them. Next time I cut and splice."
