V8Roadsters supplies a very nice fuel line kit for the LFX. Very similar to their kits for V8 cars, it includes a Corvette filter, EFI fittings throughout, and assembled braided lines to replace all the factory lines in the car:
Dropped the fuel tank and took a look at things. The EFI fittings are very cool but they only work with the later-year fuel hard lines. Not a problem at the engine side because the LFX has the correct lines, but at the tank things need to be switched around since mine is an NA, so I need to swap to NB bits there.
We had a junker NB sitting beside the shop, so I pulled the fuel pump assembly out of that. Had to do a little mix-and-matching of parts and as well as carrying over my Walbro 255lph pump to the NB fixture:
Using the NB’s fuel pump fixture, the EFI fittings fit the hard lines perfectly:
Lines attached, the tank is ready to go back in.. this pic is after lots of scrubbing of the fuel tank to get it clean:
With the tank reinstalled, all that’s left is to mount the filter and lines. Made a small bracket to hold the filter in place (don’t have a pic of it), and the lines are routed along the inside of the frame rail. V8R says that they typically run the lines down the driver’s side, but I found that running them down the passenger side I was able to shorten the line length by 12″ (the easy route is to leave the line as-is and run down the driver’s side):
Close-up of the attachments for the fuel line – these adel clamps are included in V8R’s kit. This is the front-most mount, I added the small stand-off to move the line away from the frame rail so it cleared the hard brake line that you can also see running behind it, which I ran at the same time:
The end of the line curves up over the transmission and attaches to the LFX’s fuel hard line and that’s it, fuel system is done. Rear subframe and diff are back in the car too.
