Good morning,
I have attached a diagram of the setup I am planning to end up with.
The difference relative to the one I already have is the addition of a lift pump near the main tank (probably a Facet 11PSI), a second HE, a CAV filter and a bypass with antireturn valves.
The idea behind fitting the lift pump is to help the injection pump getting oil but mainly to "push" oil through the CAV filter to avoid frequent filter changes, even if I fit a second HE right before it.
However I have read somewhere that excessive pressure can damage the IP, so the purpose of the bypass is to relieve the pressure. In other words, I donīt want to create pressure at the entrance of the IP. Just want to be sure there is always enough fuel available to feed it.
Excess oil would just via bypass join the oil coming from the IP and going back to the tank.
The anti return valves would prevent the IP from sucking oil out of the main tank via the return line.
I would really appreciate if you let me know of any potential problems with this setup.
At the moment fuel starvation due to excessive filter restriction is an issue I donīt know how to resolve without fitting a lift pump, but I am concerned about excessive pressure breaking the IP.
Kind Regards
