ruggedbert Posted August 28, 2009 Share Posted August 28, 2009 Are the 1/2 inch? I have a gas tank from a 75Z that I'm putting into my 240Z. I noticed that the feed and return were larger. I plan on using the 240Z feed as the new 280Z return. My question is, do I need to pull the hard lines off of a 280Z now? I plan on running a 320rwhp rated SR20det.

DeleriousZ Posted August 29, 2009 Share Posted August 29, 2009 5/16" aren't they? Quote Link to comment Share on other sites More sharing options...
Namor Posted August 30, 2009 Share Posted August 30, 2009 5/16" aren't they?yes they are and I believe the 240z lines are 1/4" I would definitely upgrade your lines, whether it is to stock 280z lines or aftermarket. I'm in the same boat (well, except I have a 280) and can't decide between my stock 280 lines or aftermarket. Quote Link to comment Share on other sites More sharing options...
ruggedbert Posted August 30, 2009 Author Share Posted August 30, 2009 Thank you! Will 1/4 work for the return line? R Quote Link to comment Share on other sites More sharing options...
