Original Blueprint and Gallery Views
The retained Alpha 427002 drawing dated November 13, 2017 specifies approximately 48 US gallons and a 53 x 24.75-inch plan for this blank shell. The main body is 9.25 inches deep, with a 1.75-inch lower end feature extending the maximum depth to 11 inches. The rim is 3 inches deep and the inset lower body is 21.75 inches wide. The lower section is 4.13 inches wide with a 5.5-inch terminal run. Allow clearance for the stepped rim and lower profile rather than treating the tank as a uniform rectangular box. The original drawing corrects the previous 48.5-gallon capacity copy.
The four shadowed views and native rotatable model reconstruct this individual print for 427BLANK. The terminal flat length and transverse position of the lower feature follow the depicted outlines and are illustrative where not separately dimensioned. Natural polyethylene color and finish are illustrative. No ports or fittings are added. The underside view is flipped for display. Reference dimensions have ±1/4-inch tolerance and capacity is approximate. Use the retained original drawing and exact part identity to verify fitment; this is not measured manufacturing CAD.
