I know the SUL's are 2 micron filters, but what is the difference between a S3240TUL and a S3240? Is the TUL the filter that originally came with a metal bowl and the 3240 with a clear bowl? If replacing are they interchangeable?
Also, been reading about guys running a 2 micron filter behind a 10 micron on Yam HPDI O/B's. Anyone doing this? Reading conflicting things as it seems Yam doesn't recommend it yet some swear buy it to keep the VST from clogging. Thanks
