You are building a new motor, and want to use a tired $100 fuel pump? Why not upgrade the fuel system with the build and have piece of mind?

The fuel pump is less than a yr old. Its just a factory replacement.

How much HP are you building?

The stock fuel pump is fairly stout for volume. However it is sometimes bottlenecked by the stock fittings. The inlet size is fairly large and will accept AN -10, the outlet can be bumped up from the stock 3/8 to AN -8 for better flow. Beyond that KE makes a housing that will bolt up to the stock pump and allow AN -10 fittings.


What size line do you have running from your tank?
