I gave Classic Car Accessories a call, enquiring if one of these filters would work for my old Farmall M tractor. I was worried about the flow rate through it as it's a gravity flow to the carb. Craig was good, went out of his way to test it under the tap for me. Only took a day to arrive, and it works really well, and easy to dismantle and clean the internal mesh filter. Great product, and excellent service. Cheers Stu Kneebone
