Nineteen gallons is an oddly specific capacity, and that specificity is the Ronco Plastics B183's reason for existing: it is the tank for the compartment where a 20 gallon molding will not quite close the lid. Shipping at 24 lb, it is a marine fresh water molding in FDA-compliant polyethylene from Ronco's Tustin, California plant - one of the many precisely-shaped tools the company has cut since 1974 to fit boats as they are, not as tank catalogs wish they were.
The B183 ships with fittings installed per order: spin-welded or threaded, at the sizes and positions you mark. Use that freedom deliberately - align the fill with the shortest hose run from your deck plate, put the vent at the compartment's high point, and set the pickup where the tank drains driest at rest and under way. The dimensioned drawing below is the worksheet; the fitting planner on this page turns your marks into the build order.
Full, it holds about 158 lb of water - the quiet arithmetic of 8.34 lb per gallon - so mount it on a flat base with a proper strap.
