Not that I can recall, no - they should just have a fuel filter and water separator up on the engine - fleetguard numbers FF5052 and FS1280 IIRC (wow, how many of these have I serviced in my life... :D ) then straight into the pump. The QSX15's have 2 of those strainers - there's one in the spud on the fuel filter too - same part number, everything. You can clean one out and still get hard starting - I think it's their just to catch you out ;). IIRC there is a 14mm hex head screw needs removing to fish them out, but I haven't done one in some time.
