This stinks. My 83 K5 is set up with TBI with an in-line fuel pump. When the tank rusted through, I ordered an EFI tank to get the anti-slosh baffles. I decied to just keep the in-line pump instead of getting the in-tank setup, partly due to laziness and partly because I kind of like how easy it is to replace the pump right now. But now it looks like the baffles interfere with the old style sending unit. Has anyone else been through this? The sending unit will fit in backwards, but then I'd have some crazy routing to do to get the hoses all installed. What the heck should I do? I could try to return the tank, which would be a huge pain, plus then I'd lose the anti-slosh. I'm leaning towards the backwards install, but I'm a little paranoid about the extra long hoses chafing on stuff.
