Fuel System Diagram

While we're doing diagrams I thought I'd share this one too.

Drawing this diagram helps me to organise and better plan prior to installation.

I hope someone finds it useful.

You will see that I have not included a Gascolator. (unlike Pete).

All the advice both from UL Power (and Vans) says that unless you can fit a Gascolator at the lowest point in your fuel system then it is pointless.

The lowest point in a Twister is the rear of the fuel tanks (as it is a taildragger) which is where the factory say to fit the drain valves.

This is where you drain off any water that may have collected in the system (the low point).

So fitting a Gascolator to a Twister on the firewall is pointless - even the fuel screen which normally acts as a final filter before injection is pointless as it is coarser than the fine filter supplied by UL Power and fitted further upstream.
