F. FUEL LEVEL ADJUSTMENT -For models without an external fuel level adjustment.

(1) Some 2300 and 4150 models have an access on the end of the fuel bowl and a sight plug on the side opposite the fuel inlet. Remove the sight plug and check the fuel level at the sight plug port with the engine running. The fuel should be on line with the threads at the bottom of the sight plug port. If the level is not correct, STOP THE ENGINE. Remove the access hole plug, insert a screw driver in the hole and bend the float tab up or down, to raise or lower the float. Recheck the adjustment .

(5) With the car on a level surface and the engine running, the fuel level should be on line with the threads at the bottom of sight plug port. (Plus or minus 1/32 inch tolerance.)

(2) On models without an access hole, with a sight plug, check the fuel level at the sight plug port. To re-set the level,remove the fuel bowl and check the level with the correct dry float gauge. A change of 1/16 inch of the dry float setting will alter the fuel level 1/8 inch.
