What is the latest greatest way to get a long  lasting seal on the access plate to tank and the sender flange to plate  junctures?

 Last I heard Van said to just use the cork gasket  material for the plate and the rubber gasket material for the sender.   

 Over the years I've heard some guys use just  proseal and others use the gaskets with proseal on all surfaces.

 Removing a tank to correct seepage is unthinkable,  however, having to remove the access plate to get inside the tank seems possible  should a leak elsewhere in the tank develop, hence the dilemma.

 TIA,

 Jim Stone

When I built my RV-4 I used the  gaskets Van supplied,,,,, Big mistake. I cleaned it up and re-assembled it with  Pro seal, haven't had a problem since. My Rocket tanks are Pro Sealed.

You can get a pro sealed access  cover off with a putty knife.

Thanks for your response.  What about for the  fuel sender units (vans), use the rubber gasket by itself, proseal by itself or  combo?

 Thanks,

 Jim

Jim,

  

 I made gaskets for both the cover plate and the  sending unit from good quality gasket material from the aviation aisle at  NAPA. I also used a non-hardening gasket sealer (Tite-Seal Medium Weight). I  have never had a leak, but did have to remove the cover plate (and the tanks)  when the slosh compound came loose ten years later. The cover plate was easily  removed with little effort and the clean up of the surface to reseal was also  easy. I don't know how easy it would to clean up old Proseal and reseal if  you had to remove the cover plate.

  

 While on the subject, I'm not sure why one would  need to remove the cover plate while the tanks on the airframe. The access is  very poor and I can't imagine why removing the cover plate with the tanks on  would be advantageous.But then again, I've been told before that I have no  imagination!

Proseal it with NO gasket. And be sure theres  a little proseal under the screw heads
