Cork VS neoprene gasket in gas gauge
Hi fellow Ford Barn members:
I am in the process of replacing the gas gauge in my 31 roadster and I am undecided if I should use cork or neoprene gasket in the opening of the gas tank. Which one will be more ressistant to the ethanol? Also which is the best sealer to use on these different gaskets? Andrew's just mentions a gasoline proof sealer in his book. Any help will be appreciated. Thanks, Henry's 31 |

Re: Cork VS neoprene gasket in gas gauge
I also find cork more fuel proof. I have used permatex paste teflon thread sealer as a gasket sealer for fuel items. Gas doesn't seem to effect it. Don't use RTV silicone with fuel.

Re: Cork VS neoprene gasket in gas gauge
I used cork with a very thin coating permatex seal several years ago and it has held very well.
Now, on the other hand, use the neoprene float as opposed to the cork float in the tank......It won't soak up gas in time. |

Re: Cork VS neoprene gasket in gas gauge
cork gaskets and a brass float similar to that used in the zenith carbs......search old forms and you'll find out all the particulars....

Re: Cork VS neoprene gasket in gas gauge
Use the cork gasket set which also includes the thin brass ring.

Re: Cork VS neoprene gasket in gas gauge
Cork float BUT - neoprene gasket set on the gauge. Good combo - old and new.
Be well - SHEC |

Re: Cork VS neoprene gasket in gas gauge
X2 what Mitch said.
The cork on my float still works fine, but for sure use only cork on the glass lens. |

Our neoprene gaskets swelled up, and stopped the gauge working properly. Maple syrup - no leaks, and doesn't dissolve in petrol.

Re: Cork VS neoprene gasket in gas gauge
Hi Al: As above, use the cork and the brass seal, never used or thought of the "syrup" idea !!!

Re: Cork VS neoprene gasket in gas gauge
Ethanol swells the neoprene. real gasoline doesn't seem to.

Re: Cork VS neoprene gasket in gas gauge
I guess we are lucky out here in CA as we don't have a lot of ethanol fuel. Still would not purchase it if readily easily available! I have been lucky since my American made Neoprene set has been in the car for over 25 years.
Sorry to hear of others having trouble but good to see the original cork set up (as designed) still works fine - Thanks folks - SHEC |

Re: Cork VS neoprene gasket in gas gauge
No ethanol in our fuel, and the neoprene swelled until the guage would jam showing full, unless you pushed the float down with a stick - the same one we had to use to measure the fuel level
I pulled the gauge back out, used a scalpel to trim the swelled part off, and all is OK, but I'd either use the cork, or some decent fuel-proof material to make my own next time.
