baddriver Posted June 6, 2003 Share Posted June 6, 2003 I have an early 74 Z that I am planning a fuel injection swap in. As I understand it, the current tank cannot be used without some sort of fuel resevoir because the tank isn't baffled suffficiently for a fuel-injected application. I searched the archives, and what I think I have learned, is that the '75 Z has fuel injection, and still used the full size spare, so that tank will fit on my 74, however, in 76 the Z switched to a different spare, and a larger tank was added that will not fit my car. Is this correct? Are other people using the early FI tanks in 74 and earlier cars? Thanks for your help, Jeff E. Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted June 7, 2003 Share Posted June 7, 2003 yep, you will have no problem with the fit of that tank. I belive its 77 and up that is a differnt shape Quote Link to comment Share on other sites More sharing options...
dmyntti Posted June 7, 2003 Share Posted June 7, 2003 If you remove the spare tire well would the later tank work on the earlier car?. I have an early 71 that I am putting an LT1 in. Quote Link to comment Share on other sites More sharing options...
baddriver Posted June 9, 2003 Author Share Posted June 9, 2003 Dmyntti, I believe if you remove the spare tire well, you would probably be able to add any tank you want. If you remove it completely, I've seen at least one Z using the camaro fuel tank. The main advantage to that is that the tank isn't 30 years old. Jeff E.

Guest shauno_ Posted July 2, 2003 Share Posted July 2, 2003 One thing I noticed with my 75, was that it still ran dry when i was cornering hard with approx a quarter tank of fuel. So i would push it around a sweeping left hander and the damn thing would starve and lose fuel pressure... So, i think that these tanks are not all that desirable for an efi swap. Sure they will fit and have bigger lines but they still don't seem to have sufficient baffles inside. Personally I would recommend going to a sump underneath your existing tank. Sure you have to do some welding and fabbing but it would be a fail safe route. Especially if you're boosting you engine. It's not that expensive for the extra security and the feeling that you will never run dry around a hard turn. Quote Link to comment Share on other sites More sharing options...
