      Are these pumps repairable? I have one that is not pumping fuel. Are there kits available or do I need to retro fit a new one?

      Thank you for your advice.

          Do you have a link to that material? I looked on Amazon and ebay, but the thinnest I can find is 1/16″ (.062)

          Is this the stuff?

                Ideally the material should be reinforced with a mesh.For whatever reason it seems rather difficult to source.  A year or two ago I ended up purchasing from an e-bay vendor in the UK.  Couldn’t find what I wanted anywhere else.  It’s still available from them:

                https://www.ebay.com/itm/313421676905?hash=item48f9634169:g:QhsAAOSwqTVgLBqM

                I’m not sure what’s going on with the pfs-ware link that Buccaneer posted.  I sent them a check earlier this year and my letter was returned as an invalid address.
