This 2 piece needle/seat is made in the USA. It has a larger inlet orifice than the stock parts. The "needle" has a much larger diameter than the original. On the end of the needle is a soft, Ethanol resistant tip. It was designed such that it would let small pieces of debris to flow through the seat, and past the needle to avoid a sticking float. Mike has been using them for several years in all the restorations he does, with good results. This 2- piece needle and seat is part of our rebuild kits. We are now offering the Grose jet as an alternative to the 2- piece needle and seat shown here. The Grose jet can be found in shopping cart at $15.95/ea.
