zdude1967 Posted August 20, 2016 Author Share #13 Posted August 20, 2016 Thanks for the advise everyone. The tank is clean, it has been redone. I actually tried a vacuum attached to the fuel line to suck the fuel into the upper part of the line but only got a gas bath. Trying again later today. One other question, I have replaced the fuel tank float seals and now the tank leaks from the float area at 1/2 tank or more, any suggestions how to fix this. The float hardware is new from motorsports.

Mark Maras Posted August 20, 2016 Share #14 Posted August 20, 2016 Is it leaking around the o-ring or at the elec. connections?

zdude1967 Posted August 21, 2016 Author Share #16 Posted August 21, 2016 could the carbon canister be an issue with the fuel not being pumped to the carbs. Does the canister if it is not functioning properly make the fuel system have air leaks thereofre the fuel pump is drawing air rather then fuel Link to comment https://www.classiczcars.com/topic/55997-ran-out-of-fuel-260z-fuel-pump-wont-bring-fuel-to-carbs/?page=2#findComment-501550 Share on other sites More sharing options...

I remember Cliff @siteunseen talking about how tight the ring was supposed to be.

zdude1967 Posted August 21, 2016 Author Share #18 Posted August 21, 2016 I thought it was- I will try cranking it down some more in a bit. It seemed to not have the option to crank down any tighter it was more of a turn it until it goes under the lip intended to hold it in Link to comment https://www.classiczcars.com/topic/55997-ran-out-of-fuel-260z-fuel-pump-wont-bring-fuel-to-carbs/?page=2#findComment-501553 Share on other sites More sharing options...
Zed Head Posted August 21, 2016 Share #19 Posted August 21, 2016 Sounds like you're still having problems getting the pump to pump. It really shouldn't be that difficult, unless there's a problem with the pump or the inlet lines to the pump. If you want to try some things without disassembling everything, you could remove the valve cover and actuate the pump lever by hand. The pump mechanism and drive eccentric are right there, easy to get to. Disconnect the fuel lines, place the inlet side in a cup of gas and the outlet inside in an empty cup and see if the pump moves fuel, by moving the lever. That's all the camshaft does, is move that lever back and forth. Turn the engine over so that the lever is on the small side of the eccentric so that you're operating it in the normal rage of motion. Who knows, the eccentric might have fallen off or the lever might have broken. Quick examination and test.

zdude1967 Posted August 22, 2016 Author Share #20 Posted August 22, 2016 OK- I got it going by putting air into the return line to the fuel tank- this pushed the fuel through the lines till all the air was out.
