Long story short the car went in the shop for fuel pump/sender replacement and the tabs broke off the crossover fuel line leaving what looks like holes in the connector. Is there any source to get the internal lines or do you need a whole new crossover tube? I’ve heard horror stories of the tabs breaking off when doing this job and it happens go figure. Do these tabs just get brittle and break or what? Couldn’t have been broken before or the car won’t run like now… Thanks
Check out M2 Performance Engineering. They make a conversion kit for the lines you’re talking about. I don’t know anything about them but I saved that info for possible future needs.
Thanks, are these tabs known to get brittle and just crack when properly removing the crossover? If they weren’t broke before and the shop breaks them who do you guys feel should be responsible?
The tabs that are known to break are on the fuel feed tubes that are in the tanks (1st pic). Don't think you can hold the shop accountable. The tabs are what secure the line to the tank outlet so it doesn't push into the tank when installing the crossover. Some have reattached the line to the tank using small zip ties.
2nd pic is the crossover fuel feed line that does not have any tabs to break. Make sure you know which tube is broken. They are all discontinued and hard to find. Don't buy salvage used ones. Do a global search of "GM 10337588" for the crossover tube line.

It is nearly impossible to not break the tabs. When I dropped my tank to put in a Z06 pump, there were some broken tabs. I just used some small zip ties to secure the tubes where the tabs previously did. Use some small needle nose pliers.
Even if the zip ties come off or break, as long as they hold while re-installing the tank and the internal piping, that is all that is needed. Once the interal pipes are connected, they will stay connected and in place.
Well I got the car back today, the shop “repaired” the connector but recommended a new fuel crossover and would replace it free after I find one and purchase it… the car is hard to start after sitting awhile for a few minutes but starts right up if you shut it off so I’m wondering of that line is causing fuel pressure issues bleeding off? After all this to fix the gas gauge, it still doesn’t work and i’m really bummed plus have to fork out even more money for a crossover line now. I’ve been without my car for over 4 weeks and get it back only for it to have to go back in shortly and spend even more money on parts.
Make sure they put in the correct fuel level sensor. There was a change in 2007.
Yes I read there was changes during the 2007 production year. I can remove the error code in hp tuners and it works though same as before. Found out the shop only replaced the driver side fuel pump and sender because they said the passenger side was unavailable at the time and that was the bad one. I really didn’t even want it fixed because of the crossover tube being known to break and it did work before. Found some used crossover tubes on ebay in good condition, going to have to go that route.

Given the amount of labor involved in this repair I don't understand why a shop would put it back together and then offer to redo the job for free. You keep referencing the "fuel crossover", is this the crossover tube?
Based on your profile you have a 2007 Corvette, you stated they replaced the LH tank pump assembly which would include the fuel level sensor, the RH tank fuel level sensor is PN 19420830 and is available. Did the shop replace the RH tank fuel level sensor?
When talking fuel lines there are three components to this 1) LH tank pump to crossover, 2) Crossover Pipe and 3) RH tank pump to crossover.
LH tank pump to crossover - PN 19436042 and is available
Crossover pipe w/ lines inside pipe - PN 19436041 and is available
RH tank to crossover - PN 19431776 - Discontinued but there are good used options on eBay
No reason for your car to go into a shop for a fuel level reading issue and come out with the same issue.

They only replaced the drivers side sensor and the passenger side sensor was the bad one, said the part was not available at the time but now it is… stinks.
Yes, a new tube includes the feed line....you can (or at least you could in the past) get the inside feed line separately. The corrugated stainless tube gets stiff over time, so is recommeded to replace the whole pipe for ease of reinstallation.
Wait until you look up the 4 orings to replace on the pipe.....150 bucks and don't come with a new crossover.
Do I need four of the yellow and black o rings? What about the smaller o rings on the fuel lines, is there a part number for those? Thanks
Yes you need GM PN 10376929, this comes with two rings, and you will need two sets. I have read on this forum that the small rings at the fuel tank are considered reuseable, but the below link can shed some light on sourcing those. If the repair shop replaced the large orings I would reuse those if not damaged.
Based on what you have posted sounds like your shop just needs to drop the RH tank and replace the fuel sending unit. You need a 19420830 Sensor Kit for $79.88 and a 10376929 Fuel Tank Vent Pipi Filler Oring Kit for $67.09, all in @ $146.97 assuming your shop is doing the job for free labor.
