I have an 85 iroc 305 tpi. My fuel pump went out on me and i am not sure what to replace it with. I know that people like the walbro, but am concerned about their no warranty and possible decline in quality. However, it is half the price of the napa replacement from ac delco. I am also considering turning mine into a 350 tpi so may need some higher flow. What do you think is the best pump out there, that is not super expensive? thanks
