Yes and no. The sediment bowl is already a filter, presuming the gauze disc has not been discarded. When new it was perfectly adequate to cope with both particulate and liquid contaminants in the fuel. It is a visible indicator of fuel flow and condition, as far as the fuel is concerned and is easily cleaned if excess contamination is observed. Your fuel tank is the reserve for the carburettor. So, no, it is not needed for that. By all means you can replace it with a SUITABLE low pressure drop device so as to retain flow at the low pressure head of a near empty tank but, I would ask, why do that? The existing item was, and still is, a superb piece of kit to do the job it was designed for - fuel tap, filter and sediment indicator. Your new in-line filter will not indicate when the pressure drop is too high, will not prevent blockages any better than the former and will filter out smaller particles (which would do no harm anyway) and may block prematurely with liquid contaminants or pass them through to the carb causing extra running problems. IMHO bad move, but your choice. Regards, RAB
