I have a Tour Tank under my MotorTrike body (my other trike) mounted to my homemade sub-frame work. It really is a "Coyote Oil Tank" from Tour Tank which they sell as well. Just suited my needs better. Good tanks, seals good, has pipe thread "bongs" for attachment of electric fuel pump. Just add a toggle switch to handlebar or fairing pocket. Learn how much "time" is need to drain aux. tank by either having a dash clock or wrist watch.
The other tanks they have are more for gravity feed for motorcycle use (1-3.5 gals) and one needs to put a "T" and a on/off fuel petcock in the fuel line. In this set-up, one uses the aux. tank 1st (most are mounted to rear seat/rear rack) THEN uses the stock gas tank fuel last. As this gives YOU a way to know "when" to re-fuel as it's just like a normal turn on the reserve for operator.
Some guys have been using Harbor Freight/Pep Boys/Walmart air pump tanks which cost about $25.00 for re-airing your car tires. They dis-assemble the unit... and add bongs for fuel outlet and add a gas cap. Their mostly steel units but some aluminum...check with a magnet. Don't throw the pump away...you can still use it.
