Ameri-Kart W1496 RV Water Tank Replacement & Fittings Guide

Asked by TerryAsked on June 10, 2025Answered by Elkhart RV Parts
Customer Question

Is the Ameri-Kart W1496 RV water tank actually 26 gallons instead of 33? Is the 31 Gallon AmeriKart W1315000 a reasonable replacement given its slightly smaller flange width? Also, does the $20 charge for spinwelded 3/4" female NPT fittings reflect their true cost? Finally, is the universal fresh water fitting kit a reliable and cost-effective alternative to spinwelded fittings, and which fittings should I select?

Expert Answer

The Ameri-Kart W1496 RV water tank has a true capacity of 26 gallons, not 33. The 31 Gallon AmeriKart W1315000 tank, measuring 46" x 31" x 7-1/4", is a reasonable alternative if you can accommodate its slightly smaller flange width (about 5/8" less). Regarding spinweld fittings, the $20 charge per fitting reflects the installation process and the quality of fittings used, which are higher than standard retail prices. If you want a more economical option, the universal fresh water fitting kit is indeed a reliable alternative since RV fresh water tanks are not pressurized. Ensure that your cart includes the correct 1-3/8" and 3/4" fittings compatible with your tank connections. For additional options and lead times, you may also consider using the tank finder tool on our website.
