I agree 100 percent RRR. When they were new they didn't have this problem. But then we had some pretty high octane (REAL) gas back then also. I already replaced my fuel pump once because of this issue and it's kind of hassle if the damn bio-gas is messing up the mechanical pump. Either way if the electric pump solves the problem it won't matter. My car only has issues on start up after that it runs really great!!
