Re: Changes to fuel system for fuel injection

Sam Hoskins


I have a fuel injector mounted on each intake tube. Here is path each drop of fuel takes:

Header>aft, behind pilot>Walbro fuel pump>10 micron high pressure filter>forward, out to firewall>Injectors>Back aft through firewall>Pressure regulator>header tank.

I use the plans setup for transferring fuel from the main tank to the header. Same with the Q-200 ram air vent tube. Look in my photos in the Q-list for a schematic before I installed the fuel injection.  Look in my blog for photos of the engine and other fuel injection components.

Here is something to think about. Any leak in a connector, or hose connection, will spray 40 psi fuel into the engine compartment. But, so far, so good.

For those running fuel injection in their Q2s, how did you end up setting up your fuel tanks, lines, vents, returns for the change. Toying with a few ideas but curious if anyone else has gone down this road. Essentially we're trying to eliminate the use of the header tank as a header tank and either integrate it into one single storage solution with the main tank or setup as two separate tanks with a selector. Open to thoughts and criticism here.
