Advice Needed--Fuel Flow Sensor Placement

kbecker · #1 11-05-23, 01:08 AM

77 337G, normally aspirated.

I am upgrading my engine monitor and this time including fuel flow sensors. My mechanic and I looked at the engine compartments today to determine how to re-route the fuel lines to accommodate the sensors.

Has anyone installed fuel flow sensors? If so, how did you re-route the fuel lines? I would like to see how others have done it before ordering new fuel hoses, putting holes in baffling, etc.

Thank you in advance,

Kevin

Kevin,
On my 77 NA 337, I had a shadin sensor plumbed in between the throttle body and flow divider (spider). So I just spliced the new red cube for the GI275 EIS in the same spot, immediately above #1 cylinder, held in place with adel clamps. Positioning & plumbing is the same on both engines. I put the fuel pressure sender on the flow divider.

Might need a snubber for fuel pressure if your new gauges are as sensitive as mine are.

PM for more details or you want to chat.
