I can only reiterate what my customers say, buy cheep; buy twice.
We make each of our tanks to order and can also upon request and provision of any sender unit fit one during the tanks construction this way avoiding any fitting issues, we can then pressure test the tank and make sure that it is right first time.
I have a pending order from Italy requiring a sender unit, so I will have some photo's when the order is confirmed and in production.
I would advise though that prior to any fitment that sender units are wired to the scooters electrical circuit and fully tested in a mock setup.
Looking at the tanks on the market right now we are not the cheapest but we are also not the most expensive either, as I have previously stated on other posts on facebook groups, it all boils down to the customers choice and budget.
I've had a Diablo tank in my GP for the past few years and have never looked back and since taking over the business from Alan Terry the customer feedback is second to none and demand even greater.
