Other Fuel System Hoses Lines/piping, And Fittings Problems of Chevrolet Suburban

Engine light on-diagnosis p0455. Last 2yrs took to many repair shops. Replaced, gas cap, purge valve, canister valve, charcoal canister. Took to chevy. They replaced purge valve because they said other mechanics used non chevy parts. Engine light came back on. Chevy did smoke test and swore it was the fuel sensor cost $1200+. Engine light back on after a week. Another smoke test and now pressure test blew a small section of fuel tank where it now leaks. Chevy said the seal most likely not seated properly and I need a new fuel tank about $1000. But they can't guarantee this is the cause of the engine light. I can't afford another $1000 especially if this doesnt solve the problem. Already spent thousands fixing different parts. Vehicle gets about 12mpg and has in the past lost power while driving as if not enough fuel is getting through but that hasnt happened in some time. Wonder if anyone else having this p0455 issue?.

While replacing the rusted brake lines on my Suburban (see tracking number 11066863), I noticed the fuel lines going to the fuel filter were also terribly rusted. It appears the rust emanates from the plastic clamp that secures the fuel line to the frame. The tube nut that goes into the filter appears to be frozen with rust. Salt and dirt are trapped in the plastic clamp and nut, which is impossible to wash out. The fuel lines on top of the fuel tank are likely to be rusted, too.

From 2017-present engine light is on and has code p0455. While driving down the road vehicle drives a bit rough and on at least 8 occasions it has lost power while driving down the road. Almost feels like its going to shut off. Three smoke tests were done, one at a Chevrolet dealer in 2017. So far auto repair shops have replaced 1)gas cap, 2) purge valve 4 times, 3) fuel sensor above fuel tank and we diy replaced carbon canister and vent valve solenoid. Still the problem persists.

Takata recall: it's been over 9 months since I received a recall notice regarding my Suburban. I have made several calls and still no fix for the problem. I have also had problems with the emission sensor caused by gas tank cap. This appears to be a problem for all Suburbans. I also experienced a loss in power with this vehicle while on the highway. The stabilitrqck light came on and I was able to safely exit the highway. Could have been a severe accident if inwas not near an exit.

The rear fuel tank strap broke by the bolt. The strap then pivoted down onto the drive shaft. The only reason the tank did not hit the road is because of the strength of the fuel filler hoses from the gas cap.

Fuel was pouring out from the top portion of the fuel tank, on my year 2000 Chevrolet Suburban 2500 where the line goes into the pump at the tank. There was a serious potential fire hazzard from fuel pouring onto the exhaust system while driving. I had a certified service station remove the fuel tank, and perform a smoke test. They found the leak coming from the fuel pump assembly. Replaced fuel pump assembly, and fuel filter as recommended. Reinstalled tank, and road tested for any leaks, none found. Total parts, tax, and labor came to $935. 05.
