Fuel Injection Tank question
 

I have a 1978 GMC K25 from Arizonia that I am going to resto-mod if you will. I have a Dana 60 rebuilt and ready to put on it and currently am taking the body off the frame so it can be cleaned up and painted. When I put things back together I will eventually put either an LG4 I have laying around, or the 8100 Gen VII Big Block I am removing from a 2003 2500HD - leaning towards the 8100!

Here is the issue, I know I can run the 1987-1991 TBI tank selector valve and TBI tanks with 1996-1999 Vortec pumps and sending units. The problem is I cannot find a fuel filler hose that will go from my original fuel filler to a tank with the larger opening. If I had a 1979 or later I would replace the fuel filler neck to a 1982 and later, but my current fuel filler necks are in great shape as is my original box.

What are folks with the 1973-1978 boxes doing for fuel injection tanks? Thanks. Tom

This goes back a few years when I thought I had the same problem. I put the '87 fuel tank in my '80 C10. The solution is quite simple. Take the original hose off of the steel fill tube neck, and use a Gates #24716 fuel hose. It has the same ID's as the new tank and your fill tube. Just cut it to the same length as the rubber hose your truck originally has
