Been looking at prices on race gas the past few days and that stuff ain't getting any cheaper. Looked thru several other threads but I wanted to get some opinions. I've got a Weldon 2345A pump, 2040 Regulator and a Weldon 40 micron pre filter and a 10 micron post filter, and Mike Moran 235# injectors. What else is required to run E98? Advantages/disadvantages? Any differences in the size fuel/return lines required? Anything else that would have to be changed?
