GPW Fuel Question

Ok! I finally took the leap and purchased a 1943 GPW, Now what do I need to know about fuel will I need to use additives or is regular gas OK?

Regular gas with ethanol runs fine in mine, no additives. Don't leave it in there for long periods.

I run regular gas in mine. Like NDT said, modern (ethanol) as doesn't like to sit for long periods, so if you aren't driving the vehicle regularly, do something about it.

Thanks for the advice I didn't want to an idiot and wreck it!

Let's see some pics!

Congratulations on purchasing your jeep! I concur with NDT and Clinto. From personal experience I've driven thousands of miles in gasoline military vehicles from the 1940s-1970s on standard pump gas and never had an issue. Lots of those miles have been in Jeeps with the L and F 134 engine. One thing to consider, if gas might be in a vehicle for a while (like parked over the winter), mix in up to 5% diesel and keep the tank full to avoid condensation. I've found that small percentage of diesel helps keep the float/needle and seat from sticking and prevents green corrosion on the brass jets and passages in the carburetor, among other things.
