1) There are two different pumps that were used on these engines. You must measure your old pump carefully to determine which is the correct pump to order. This pump has a 3/8" impeller extension. If your version extends 1/2" beyond the mounting surface, give our tech support line a call for more information.

2) There will be a 50% non-refundable deposit charged to your card upon placing an order for this item. The balance will be charged when the item ships to you.

3) When you order a special order item it sets off a chain of events like Willie Wonka in the chocolate factory. Once you turn the valve the chocolate is coming down the pipe. If you then decide you want caramel, the chocolate is still going to come out of the pipe. We can't put the Chocolate back in the pipe, so someone is going to have to eat it, and it's not going to be us! Your order can't be canceled, returned, or magically changed into caramel, so please order carefully the first time!
