Overall Assessment

Customers recommend the product for its durability, practicality, and compatibility with various car models. It stands out for its material quality, being described as "better than steel," and features resistance to rust. Despite some requiring adaptation for mounting, users noted its standard 5-hole mounting is compatible with later sending units. The tank is particularly suited for '39 Ford coupes and '40 Ford sedans, but may not fit all models, such as the 1940 Ford TCI chassis with rear sway bar. Installation is described as light and easy, making it an ideal choice for street rod projects.

Very nice gas tank

Make sure to follow the mounting instructions. The tank has the standard 5 hole mounting for the later sending units. If using the original 6 hole sender you will need to purchase an adapter. If the original float is too large you may have to find a smaller float to install through the hole in the tank and adapter. This tank was installed in a '40 Ford tudor sedan. Since the stock floor pan in a sedan is different than a coupe you will have to route the gas line a little different than in a coupe.

Although I made an error in my research and this tank will not fit between the rails on a 1946 ford truck as it seems the frame width changed in 1942 but it does still fit my 1939 ford coupe and I will be using it as an upgrade

Overall the tank was an easy exchange. the only thing I didn't like was the bolt holes. difficult to get bolt washer and nut to stay in the slot during their installation.I would still recommend the tank as a replacement.
