The original filter uses a banjo connection, but the Filter King one has a spigot connection (at least, mine has).
The standard pipe won't fit unless you cut the banjo off and try and ram the end of the pipe onto the spigot. That might be difficult, as you can't really heat up the whole filter to get the spigot hot as suggested above.
I made my own pipe up with braided fuel hose from Demon Tweekes.
