I've been using a 15L I bought off of Amazon. I know full well it may die at any moment, but I've probably gotten my money's worth already. Hoping it goes a lot longer though.

I got the 15L instead of the 10L because for an extra $40 (at the time), it came with two additional pressure transducers, and the added size doesn't hurt. Fits four carburetors ezpz. Glad I got the 15L because I was able to fit a fairly long SV650 carburetor into the unit without taking apart the linkages connecting the two carburetors.
