I have a leaky gas tank in my S10 and was just given a NICE tank from a 1995 that was pulled to install a fuel cell. I've only seen the bottom of my 1991 tank and I am not sure if these tanks are the same, has anyone ever done this? If not does anyone know if these tanks will interchange? I plan on installing a Walbro 255lph pump and using the 1991's tank hanger if that matters. Thanks in advance everyone.
