RE: Step by step pulse fitting installation.
This thread is old dated info. There is a better way.
That is exactly how it should be done. You must go into the bore. Been trying to tell everyone this for years glad to see Bonzi has finally figured out it works best also.
The top side would not even work if you went into the integral pulse hole. It should be in the bore on the topside(sides work well also)just like you have it.
I would NEVER tap into the integral carb pulse port on the bottom of the intake as that will rob the already limited pulse from the carburetors fuel pump by adding a LOT of volume and softening the pulse. Most everyone had been doing the pulse into the integral carb pulse passage way for a long while but it is far from optimal for a number of reasons.
This can cause a high speed leanout. It also allows the vacuum line to accumulate fuel in it that the topside does not. It gets it where it is accessible and not straight into the grey coil if you had one mounted there. The pump will pump the most water with the least negative affects by tapping into the BORE of the intake than even tapping the crankcase or a transfer port. I have done many tests and can absolutely guarrantee that the pulse line tapped into the bore will be strong better pulse for a water pump than you will find anywhere on the engine.
