914World.com _ 914World Garage _ Confirming Fuel Line routing

Posted by: simonjb Sep 26 2020, 11:03 AM

Hi,

I just want to confirm my fuel lines as I have now converted to a 2 port fuel pump from a 3 as I rebuild my original 2.0 Djet system. The diagram below and others seem to confirm...

Tank to Filter to Pump to Fuel Rail (Cylinder 3&4) to second Fuel Rail (cylinder 1&2) to Pressure Regulator to Return Tank line. Then a separate line off the (cylinder 1&2) Fuel Rail to the CSV. Correct?

Yep. Only difference between 3 port and 2 port is with 2 port the return line from the fuel pressure regulator goes right to the tank return, instead of the pump port.
