Sasha Member 141 Member For: 17y 3m 17d Gender: Male Location: North Queensland Posted 20/05/15 02:24 PM Share Posted 20/05/15 02:24 PM Is anyone using a Walbro 460lph E85 compatible fuel pump in the standard sender unit and if so was there any drama with higher fuel pressure / richer mixture associated with the swap?

Running standard lines and reg. The reg and return lines are just up to the job but they recommend a new reg and return lines to avoid high fuel pressure at idle. 1 Link to comment Share on other sites More sharing options...

Even though yours is as a lift pump in the tank I would imagine fuel pressure would still be quite high Link to comment Share on other sites More sharing options...

I can see an aftermarket regulator in sight.I might put a gauge on it and see exactly what the pressure difference is.Are you guys using the standard wiring configuration or have run a new power supply to the sender?

Is there anything special about the relay? I was going to run a fused feed from the battery and switch a relay via the original pump power feed. 1 Link to comment Share on other sites More sharing options...
