I posted this on hybrid Z and zcar and wanted to get your thoughts as well:

I searched the archives, but didn't find exactly what I needed. I was talking to Jerry at All Z-East in Ft. Worth about putting FI in my early model 74 the other day. Now, I had always heard that you could use the 74 fuel tank if you put a surge tank somewhere to prevent air from getting into the lines when the fuel level gets low in the tank. Jerry, however, said the problem is that the size of the return line inlet is too small. This is a problem because A. He doesn't have a 75 or 76 fuel tank B. I just got through having my tank boiled out, POR-15 on the outside and new vent hoses installed. Yeah, I should have had more foresight, but here we are. So, what I would like to know is could you have a shop weld in a bigger inlet? I mean if that is the only problem it seems like that would be the best solution. If you guys have any other ideas I am all ears.
thanks,
