2002 GMC Sierra 3500 Extended Cab V8 8.1L Fuel Line Repair Kit Dorman OE Solutions 919-841

All in all good quality fit. Only downside was the short braided lines making 90° bends. Would be nice if were made already 90°

The one bracket was not made correctly. Other than that it went in easy.

All work was done in a fully equipped home shop with tools that could be purchased at your local Hardware, Auto, Home Improvement, etc. stores.
Upon receiving, the product it appeared that the packaging was pretty deficient for what I paid. Granted, the odd configuration of the lines made packaging a little more difficult.
Removal of lines - plan on 8-14 hrs. ( Time depends on opting to cut or salvage old lines. salvaging will cost you up to 8 extra hours. Installation of new lines- Super clean and simple with a pretty ingenious sectioning job until attempt to connect both ends and work the fuel cooler spiderweb, and make the radical 90 deg. bent from the frame to the brackets on the transmission. Failure in the making.
They DO not include the two flex lines that make up the supply and return connections to the tank (the most prone to environmental failure).
The flex lines crackle then crimp when the abrupt turns are made-even if you slowly form and kneed the line. These will fail and/ or cause restrictions (lower input pressure to the CP3) premature structure failure and appear to be very susceptible to damage by a foreign object. There were two spots within the bends that resemble a hand tubing bend with the inner bend crimp and abnormal flaring. but the appeared sound. And finally- It took 3 hours to match the bracket, feed the bracket up through the steering column (which has to be slid up to the final connections to the FICM and the return lines but will not allow reconfiguration, causing the bracket to carry the fuel lines too low) , and once the lines are pulled through, you have to connect some sort of pulling device to pull hard enough to bend and severely crimp the return line, which was 3-4 inches short of a comfortable fit /and the inlet that was about 2-3 inches short.
The "spider" assembly (the final configuration in the assembly that includes the cooler and supply and return lines, was basically a full size Rubiks' cube done on your back with your head resting on the driveline, so be real patient on that one. And the clamps just don't work very well with the larger bracket in the mid/fore section requiring a nut unfamiliar to this particular application.
I realize the schematic does require a "certified mechanic"-that's a safety and liability issue.
1A Auto is a business that sells good products and has some of the best employees I've dealt with. This is NOT their issue but hopefully I can give a 5 Star rating based on the outcome.
The fact is that many customers are not "certified" but can pretty well figure out how to "take those out and put those in". We put total trust in manufacturers to honor our time since they have our cash.

There appears to be a simple solution to this and we can discus this when your QC Reps. contact me. Pulling these lines again and restabbing them is going to be another expensive and time consuming nightmare. Lifting the cab would be the evil alternative to access these components.
Compromise and avoidance will be most welcome.
Thanks for this opportunity.
I will supply photos as soon as QC contacts me.
