After reading how the fuel tank shrink due to the Adblue system in the 2015 Jetta TDI, it got me thinking... How can the 3.8gal Adblue tank repurposed (if a tune and adblue delete was done) to suppliment the 14.5gal main fuel tank? Would any of these work? -gravity feed and both tanks interconnected (if adblue tank is mounted higher than fuel tank) or -interconnect just the top of the adblue refill connector to the nearby diesel fill neck. Then connect a hose and some sort of an electric pump. or, -does the gas Jetta tank have a higher capacity due to a different shape, that might fit into a TDI as long as the adblue system was removed?
Repurpose adblue tank into 3.8gal aux. fuel tank for more range
