I went ahead and bit the bullet and purchased a Tanks Inc EFI fuel tank and all the stuff to install the first half of my EFI swap. Still remaining with carbs until I gather money for the second round in the engine bay. I thought they would send a fuel tank tube seal at least with the tank but they didn't. I didn't think to buy one. The one I have on the car is about a decade old. A little stiff but not original. Any tips and tricks to soften it a bit to make it malleable for removal? I live in Europe and this isn't a part I can just call and have on my doorstep 2 days later
