I'm putting a bigger gas tank on my truck and have a brand new rear tank for a full size blazer. It is the 31 gallon tank. I am looking for a sending unit with 3 outlets. That is how many my 85 high sierra has on it. According to LMC Truck the Blazer/Jimmy from 73-77 has one part # and from 78-82 is another part #. Not sure what the difference between them is. Never done a custom tank before so hopefully this will work. Any tips or advise will help. Thanks

If you have a fuel return coming off of the pump, you need a 4 line, if not, then you can use a 3 line. i can answer any other Q's you may have, Tom
