XII measurements should be made through the till fitting (use the same fitting for all measurements). I FAD 71(.7IE6 lllEltriJPEAi7'rf 1 Measurement 1 Is the inside diameter of the tank at the gauge opening. Measure from the. bottom of tha tank to the bottom of the fitting. This mea- surement shouid be taken prior to placing any backfill. Measurement 111 is the distance from the bottom of the tank to the top of the 1111 tuba. This measurement should be taken prior to insertion of the d rop tube. Backfill should be to subgrade3 at this time. Measurement III is the distance from the bottom of tho fitting to the top of the fill tube This measurement Is taken by drMng a nail into the t" point at a right anglo to the gauge stck. Lower the gauge stick down the fill tube fur enough to exterA bclow the bottom of the fitting. Litt the gauge stick unti the nail catches on the lip of the fitting_ Read measurement at the top of tho fill pipe. Subtract V to allow for the point where the nail is in the gauge stick. WARNING: If the answer In either measurernent 83 or b5 is in excess o1 the appropriate value shown In Table A, Iimn disaely contact Tank Technical Support (409- 756-7731) prior to proceeding with the Installation.
