Thumper Posted April 11, 2005 Share Posted April 11, 2005 Well I just got a 74' 260z for my turbo motor. Right now it has a 280z block with flat top pistons and a e88 head. Tokico struts and springs, poly bushings, 3.7 rear end, sway bars, etc... It also had tripple webers but I let him keep them so that I can install my su's and save my money for my turbo parts. My question is he ran his tripple webers with an electric pump at 3.5 psi and it was deadheaded. He just had a supply line no return (don't think the 260z has a return line). I am removing the stock mechanical pump since I have the electric one. On my carb's there are two lines going to the su's. I think I am going to just tee the supply line and put it too both of the lines. I have included pics of what i'm talking about. What do you guys think? Thanks for your time.

260ZRED Posted April 11, 2005 Share Posted April 11, 2005 A 260 does have a return line (at least mine does!) I THINK it'd be better if you used some kind of return, you don't want too much pressure building up before the SU's right?? Quote Link to comment Share on other sites More sharing options...
Thumper Posted April 11, 2005 Author Share Posted April 11, 2005 Thats what I thought but i've looked and looked and cannot find a return line. It is possible the previous owner removed it near the gas tank when he install his tripples. But even in the trans tunnel there is only one fuel line. So I think i'll hook it up dead headed just to get it running to pull it into my garage so I can get it up on jack stands and take a look.

Synlubes Posted April 11, 2005 Share Posted April 11, 2005 Both my supply and return lines on my 260 run down the pass side trans tunnel and then down to pass side frame rail in the engine compartment. Quote Link to comment Share on other sites More sharing options...
datsunlover Posted April 12, 2005 Share Posted April 12, 2005 That 'double' fuel line running around the valve cover is the feed and return.. looks like the return part has been cut off though. (the slightly bigger one) I ran my 280 with 72 SU's with no return for a few weeks, but had some issues and was afraid of possible fire as well.. it IS right on top of the exhast manifold...
