Hi all,<br /><br />I have a 3.5hp Mariner (~1981) serial number 642 S 022031 and while attempting to take off the screw on clear plastic sediment (?) bowl (part number 15303M) below the fuel filter assembley, I cracked and broke the bottom of it :mad: Have sourced the part ($6) in the US but the dealer want to charge me $40 to UPS it here to Ireland. As these parts are no longer available in Ireland my mechanic suggested replacing the fuel filter assembly with a sealed in-line one. however I would have to also put in a seperate fuel shut off valve. My questions are thus: (a) will it affect the running of my motor if I bypass the original fuel filter assembly with a new one? (b) are these threaded bowls generic, i.e. would I be able to get one from a dead engine? (c) or would someone have this part lying around and be willing to shove it in an envelope and send it on to me, obviously would be reimbursed.<br /><br />Many many thanks<br />Ciaran

Re: Fuel filter bypass

hello<br /> if this is a 2 inch long by 1 inch dia bowl then some of the yamahas and tohatsus and suzukis used the same filter set up. a dead engine would be a likly donor.the carb really does not care what filters the fuel as long as the system does not leak.

Re: Fuel filter bypass

Hi Rodbolt,<br /><br />thanks for the reply, will keep a look out, in the mean time have bypassed it with an in-line filter. seems to be working ok except that the engine is dying at idle speeds which means a carb rebuild .... has to be done. thanks again for your help.<br /><br />Ciaran
