RE: [Chrysler300]





I replaced the mechanical fuel pump in my 300G in 2006 with a new one from Summit, previous one was leaking.  I am told the modern pumps have ethanol resistant diaphragms, and mine still works fine, no leaks, almost 10 years.  Am also using an electric pump, (bought from John Lazenby's company in 2005) to prime and have had no problem with that pump either.  I am in California, and we have ethanol in our fuel, not sure of the concentration but it is not more than 10%, may be less.

 

Also, after doing much internet research on the topic of ethanol in vintage cars, have started to add 2 stroke motor oil containing TCW-3, at a ratio of 1 oz/gallon of fuel each time I fill up.  From what I've read, it offsets the negative effects of ethanol, helps with long time fuel storage, and generally helps it run better.  I don't pretend to understand the science behind it, but it seems to work fine and doesn't cost much.  Got mine at Walmart.

Just a curious thought. Are any of you guys experiencing pump failures using electric auxiliary pumps to prime your systems? I know they're low volume pumps that are generally being used but wondered whether pushing fuel through a mechanical pump could do any damage to the valve/diaphram?

Query, does Ethanol erode neoprene as well as lesser materials?  I think the newer materials being used to rebuild fuel pumps may be more resistant. Comments will be appreciated.

I've gone through numerous fuel pumps lately due to the crummy California gas.  I believe I'm replacing them annually on each car now with one exception.  Our '53 Imperial Newport still has the original pump and it always works.  Now that I've stated that I'm sure it will start to leak.  Beyond that I've had no issues.

Forgot to mention I also blame modern gas for hotter exhaust temps that cook manifold gaskets faster and dry out valve cover gaskets on the Hurst from close proximity to the HiPo exhaust manifolds.

Check out gas stations around a lake - marine facilities. we live in a lake area and quite a few stations carry ethanol free gas for all the boaters, especially the bass boats with their hi gh HP outboards.

We've been on max (10%) ethanol in MA for quite a while now, and while it has ruined a couple of fuel lines in weed wackers and chain saws, it does not appear to have damaged any of my 300s.  It has messed up the SU style carbs in my 72 MG Midget, as well as the sending unit in the gas tank and the electric fuel pump.

There isn't a single station in the state  that sells real gasoline.

I just read in Autoweek mag Jay Leno's essay on the evils of ethanol.  In my 300F I have been running a mix of 100+ octane leaded aviation gas and pump premium spiked with the normal amount of ethanol.  Has anybody in the Club experienced any problems with today's ethanol-infused gas?  Jay talks about rubber parts (in fuel pumps, for example) being eaten up and ensuing engine fires.  Terry McTaggart
