What would you expect, it's a GM product.
I have a 94 Roadmaster wagon used to drive a lot.
had serious rust on the lines from the tank
Lines had a slight angle but mostly straight.
I dropped tank
Scraped off the loose rust
Found clear vinyl tube that could fit over all 3 lines from Lowes.
Smeared PL premium polyurethane construction adhesive over all the metal lines to seal out water.
Slid the vinyl tubing over top the wet adhesive.
Idea being to keep water away permanently, and it worked.
There is around 45 psi of pressurized gasoline in the output from the tank pump.
The rest of the line is a black plastic nylon which when it gets old can snap, and snap it did on me.
Then near engine is an accordion like clear gas hose that gets brittle.
My hand bumped it and it snapped in half. Now imagine if that happens with engine running!
I replaced all the cheap as can be rotting plastic fuel line. I lost any good feeling towards GM cars after too many issues and won't buy any even used ones. I feel better about Honda, or Ram trucks with Cummins engines and even they can have issues with the 6.7L, mine is a 5.9L and it is great, not a northern truck eaten up with frame rust.
I feel like the last good cars GM made were in the 60's, everything after that is awful, and I owned a lot of 70, 80, 90's GM cars and they were all awful
My daughter bought a GMC Acadia 2011 several years ago with 120,000 miles and had to have it towed twice $1000 each time. Last time it broke on a trip trans blew up. Something went wrong with the converter, makes a high-pitched continual screech when running.
Its the trans cause we disconnect the converter bolts and engine runs quiet.
