Ethanol free gas?

Rate this post

I’ve read that vehicles using 100% ethanol will take a 20% hit in MPG. So for the majority of us that use gas with 10 % ethanol, we’re taking a 2% hit in mileage. In other words if you’re getting 15 MPG, switching over to ethanol free would be get you 15.3 MPG. Not much of a benefit, except for avoiding possible damage to fuel lines, carbs and fuel tanks.

I put some cheap gas in at a Valero station and on a short trip in 80 degree weather and it soon started boiling and running bad. I pulled over and watched gas trickle down the primary chambers after the engine was shut off. I surmised that this is happening on a lesser basis all the time hot or cold weather. What concerns me is that the gas is getting mixed into the oil compartment and causing excessive engine wear. I guess converting to a fuel injection system would put an end to this?

I had a perculation problem too. I have a L88 hood so I had room but I swapped out the Edelbrock Performer for an Air Gap performer and put in a 1/2″ wood spacer. And made sure my fuel line wasnt touching my engine. And also added a fuel pressure regulator to knock down the pressure to 5 lbs for my edelbrock carb. My problems were solved

I really like the looks of the stock hood and I think I would possibly get a single plane manifold and then cut a hole big enough for the carb and the air filter to sit above the hood. I would think that would work but still trying to think of other options first.
