i bought my 1941 Merc in Apr 19. there was already a "new" gas tank (even still shiny) installed. however, when I fill it up to the "brim", I can only go 124 miles before "running out of gas".... I carry 2 gals with me.. got that in, and then put an additional 7 gals in it before it was coming out of the filler pipe/tube. owner's manual says 16 gal tank. something is wrong when I can fill it up with just 9 gals. HELP ! stay safe thanks
 
Disconnect the battery before you remove the fuel tank sending unit. Sounds like your pick up tube is not picking up as mentioned earlier.
 
okay. will definitely disconnect my battery (I am too old for EXCITEMENT any more). I was thinking that half of the pick up tube had fallen off.... at least on this gas tank there is a plug on the bottom.... just filled it up 2 days ago, so might syphon before removing that plug. stay safe. thanks
 
If you are relying on the gas gauge to tell you how much fuel you have left, and you have a replacement tank sender, it is necessary to bend the float arm to calibrate the reading. If that doesn't fix it, the float is probably hitting a baffle in the tank, and the flange of the sender must be rotated. We always install a ground wire to one of the screws on the sender and connect it to a known good grounding point. If you are using a plastic tank, this is vital.
