The fuel plumbing for an EFII system is distinctly different from that of a gravity feed type system found in carbureted engines.
EFII requires high pressure fuel pumps which circulated fuel in a constant loop from tanks to feed rail and back to tanks. This keep fuel cool by shedding heat picked up while traveling through the engine compartment.
To resolve:
- Use low point standpipe drains for supply lines coming from tanks?
- Fuel pump module location: Firewall?
- Line routing for filters, etc.
Potential designs:
