A service element for billet inline fuel filters running on methanol. It measures 111.3mm in length with an outside diameter of 46.0mm, so check those two figures against your existing element before ordering, as billet filter bodies vary widely between brands. Stainless steel construction is the key point on a methanol setup, because methanol is aggressive towards some paper and resin media and towards plated components, whereas a stainless mesh element can be removed, cleaned in solvent and refitted rather than discarded. Regular servicing matters more on alcohol fuel systems than on petrol, since tank debris and corrosion products tend to accumulate faster. Refit with a fresh sealing O-ring where your housing uses one.
