The GX35 return hose is the fuel return line for GX35 4 stroke engines. A black rubber hose bent into an S shape, with different bore sizes and stepped fittings at the two ends and two grip ribs on the body. One end meets the carburetor return port, the other enters the tank, and unused fuel flows back, keeping the tank pressure steady, the fuel pump from straining, and the ports from weeping. It is offered in three options: the hose with 2 clamps, the hose only, or the 2 clamps only. The zinc clamps come in two sizes to match the two ends, so take the option with clamps when your old ones are bent or broken. Replace the hose when the rubber hardens and cracks, fuel weeps, the stepped fitting wears round and the hose slips out, or the grip ribs break; replace the clamps alone when they lose their bite. This hose is made for the GX35; the GX25 and GX31 from the same family are not guaranteed to fit, so compare the old hose end sizes and the ports, or send a photo to confirm.

The hose with 2 matching clamps, the hose only, or the 2 clamps only, so you buy exactly what is missing.

Q3: Which engines does it fit?

It is made for the GX35. The GX25 and GX31 are similar engines and are commonly listed together, but not guaranteed to fit, so compare the old hose or send a photo before ordering.
