If guys can just delete the fuel pump and run a line straight to the carb with no problems why is it recommended to put the grizzly valve in the carb. Looking for enlightenment. Thanks

Grizzley valve has a larger orifice, about a third larger than the stock one. It will allow better gravity flow so you don't starve your motor of fuel at high RPMs.

The stock needle and seat are designed for pressurized fuel flow from a pump - they won't flow sufficiently on gravity alone. A long hard pull up a hill or under hard acceleration and you'll starve the carb for fuel - believe me, I tried it.
While you're at it, set the float correctly and you'll love how it works.

It has a larger orifice, and, the sides of the seat are cut off in way that allows two extra holes to let fuel into the bowl without having to rush in around the needle. It is a true gravity flow needle and seat, versus one engineered to be used with a pump.


.....and, the orifice is about twice as big as the stock seat. If you use the equation for area of a circle, it shows the difference.

Ha, thank you, I was relocating my fuel pump and had to ask while I was at it
