I just installed a new fuel tank and new fuel sending unit in my 69 Camaro. I'm not getting any fuel to the carb. Yes I did put gas in the tank. I am getting what feels to be good suction at the fuel pump. Also, when I turn the key on, there is no fuel level indication at the dash gauge. How to tell if the sending unit is good?

The fuel lines are different depending on your engine and carb set up so I am limited in what I can do to help. The sending unit requires a ground to work, so make sure the ground wire is in place. My sender connects to the main fuel line with a short piece of rubber fuel line. If your is the same, make sure the line is not kinked. The tank requires a vent to function correctly. Mine comes with a vented cap. You may need to blow compressed air in the main line to free an obstruction. Make sure the fuel pump is disconnected,and you blow the air in the other end of the line, NOT in the tank.If all else fails, then down comes the tank, and a check of the sending unit itself is required. The sending unit itself is simple. Check the pipe for free flow and check the reostat with an ohm meter or test light and separate power source.

Where did you get the sending unit? Is it an original GM? I've heard bad things about the new repros. Luckily I found a brand new original GM when doing mine.

Restoman, I check the short piece of rubber tubing and there is no kinks. I will try the blow out the main line this weekend. I'll let you know. Thanks

Judd, I bought the sending unit from a dealer who buys his parts from chicago. When I bought it from him, he pulled it out of the original box and tested it, after testing the old unit. It tested fine. Maybe the ground wire is not getting good metal contact. I will check this weekend. Thanks

Hmmmmmmm, what else could it be? Just scuff the area that you are using for a ground and maybe that will help resolve the prob.
