Tirnipgreen Posted February 27, 2018 Share #1 Posted February 27, 2018 Hello...Newbie to Z-cars, Old hat with British Cars. I resurrected a 73 240z from my buddy's garage. His wife bought it new. When I first got it I drained the tank and put in a few gallons. No gas would flow so I blew out the fuel line from under the filter under the hood. I heard it "bubbling in the tank and it fired right up...! Every so often, I would have to do that line blowout and I could drive the car for 30 or so miles. Now even that won't get the gas to flow. I disconnected the fuel line from the metal line at the rear and gas is flowing. I blew out the line between the fuel filter and the back without it being attached to the tank. I blew into the tank without the gas cap on and it blew gas all over the place...! I disconnected the little return line above the "line out" hose at the tank and blew into the tank with the cap on and gas came out of the return line. I just can't get gas to flow to the fuel filter. On occasion it will flow and then recede back down the hose below the filter. I am pulling my hair out here in the north Georgia mountains....!

7tooZ Posted February 27, 2018 Share #2 Posted February 27, 2018 Do you have a manual pump or electric?Sent from my iPhone using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
7tooZ Posted February 27, 2018 Share #3 Posted February 27, 2018 There maybe enough crud in the tank to block the out line inside of the tank after some time. Sent from my iPhone using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...

Tirnipgreen Posted February 27, 2018 Author Share #5 Posted February 27, 2018 Mechanical pump. I drained about a gallon of gas just now to see if there was debris in it and...NOTHING...! I was surprised to see it run so clear. Now there is gas in the filter and it runs...! But rough. I wounder if blowing on the return pipe pushed crap into the carbs....?

Tirnipgreen Posted February 27, 2018 Author Share #6 Posted February 27, 2018 I may need to drop the tank and clean it out with nuts and bolts and alot of shaking. I have heard the filler neck can be difficult to disconnect and the RECONNECT. Link to comment Share on other sites More sharing options...
siteunseen Posted February 27, 2018 Share #7 Posted February 27, 2018 I would put a fram g2 clear plastic filter on the hose right out of the tank and watch it for a few days. My '72 was tough, all the evap hoses made it harder. That filler hose isn't too bad. I've read of people softening them up with a hair dryer. Good luck and here to help if you need any. I've done two with good results. Cliff Link to comment Share on other sites More sharing options...

SteveJ Posted February 28, 2018 Share #12 Posted February 28, 2018 If you can't maintain a draw through the pump, consider two things You have a bad fuel line that is letting in air. You have a bad fuel pump. Also, are you sure you don't also have an electric fuel pump at the gas tank? That was fitted to a lot of 73s. Link to comment Share on other sites More sharing options...
