Well here it is in the making. I spoke with Rodger at Zenith about making this and adding a BOTH selector valve. He thought it was a good idea and acceptable given it was done right. There is enough room as you can see between the number 2 and 3 nose ribs to add a faucet pump. I ended up buying pumps with AN6 fittings to help with space and  use less connectors. I am pleased with the fit but must advise this is an expensive route if you use good hardware. An access panel was enviable. You need to be able tocheck your fuel lines and fittings. Don't let the last two photos confuse you.
These are pictures of the access panel for   the bell crank. I will have more photos coming soon with the complete fit. A check valve needs to be used in this configuration. If a pump fails you don't want to be transferring fuel to the other tank! There is a lot of discussion out there about fueling a low wing aircraft. Jerry and I spoke many hours on this subject alone before he convinced me to dig into the idea further. I am happy to have a devils advocate on my side. Now for the next challenge...fuel senders.
