Petrol Injection Pipe routing


Recommended Posts

?, should,(or can) the return from the metering unit be routed to the filter. I've seen routing diagrams the show it routed to a return pipe from the filter to the fuel tank, and I just saw that Rimmer bros sells the pipes and connectors for this installation. My thinking is, since the filter is under vacuum because of the pump, and the US tanks do not have the extra inlets as the EURO tanks, this could be my work around. I plan to route the return from the PRV back to the surge tank, which along with the primary pump I'm using,( facet red top, https://www.pegasusautoracing.com/images/L/FAC-480532.JPG) should keep the surge tank full. Opinions and or Suggestions Welcome and Needed.post-13952-0-57625900-1489559201_thumb.jpg

Here is the 'original TR5 and 2.5 PI diagram from Lucas care of lucas injection.com

it shows it to both tank and filter body

 

here is the plate from the parts manual:

it shows that the return is connected to both the filter body and the tank, I assume this is to stop potential excess pressure that stops the MU working properly but would leave the experts here to advise.
