How to change get rid of primer bulb?

Fuel primer bulb keeps breaking down after only a few months, it sheds little pieces silicon from the fuel bulb into the carb causing blockages and alot of headaches. I was told the alchol content in gas(from the Gas station) was the issue. I need a replacement that will hold up to todays gas, or get rid of the fuel bulb all together. Does someone know how to mod carb to get rid of bulb?
