pro mod homelite /
 

i have a promod homelite the question is it has a pressure tap on the crankcase and one on the isoblock do i need to use bolth to run the waterpump reason im asking is i spent four hours f(*&^with the carb rebuilt it three times thinking i did somthing wrong then i noticed the crank case pressure tap and pulled all my fuel lines and pressure line to the waterpump and found that the builder of the boat had used a T to tie in bolth pressure taps .... hooked all the lines up and it fired up right away but now i have to tune the carb againe

One should be for the pump, the other for carb???
2 taps to a Tee doesn't give you any more pressure!

so ok are you saying that the one that is conected to the isoblock is used to work the carb pulse is taken from the crankcase

I am not understanding your response real well but am of the opinion as follows. (much the same as Mike I think)

Use crankcase fitting to work water pump. If your carb does not use an external pulse fitting (some carbs do - though not many) then block off the fitting from the iso block. I would avoid using a Tee fitting to join two pulse fittings.
