**Note this fuel system layout does not have a seperate feed for pump two from a second fuel filter or gasculator. It draws from only one point. Having a second feed for pump two gives you a clean filter or gasculator when pump two is turned on.
Here’s a photo of the series recommended Rotax fuel pump setup using manifolds. They had this at the Rotax maintenance class I attended in Canada. Nice and clean. These manifolds and this setup were designed for use in certified 914s. I was going to buy the manifolds until I found out they had “precious certified†costs as well. I went to McMasters and Aircraft Spruce and found “off the shelf†manifolds that worked for much less. Thanks to Dan Bish A144 for digging these out. He also has a photo in the Europa build gallery on this setup.

The check valves are there they are the small silver guys. They also are a very
expensive certified Katana part. I think this layout meets the Rotax series
requirement but obviously doesn't show the filter which is also asked for.
