Low fuel pressure switch & swirl pot
Hello,
I want to know when my main tank is failing to feed the swirl pot. I do not have provision for, not can easily add any form of fuel level sender. I
have a Facet 7-10psi cube pump feeding the swirl pot which houses a Yamaha injection pump.
If I put an adjustable fuel pressure switch (2-7psi) in the yellow-arrowed feed below, will I be able to get the switch to activate if I run low on
gas in the main tank?
 
Fuelsing around
My concern is that, because of the free-flowing overflow/return to the main tank, it might not register (enough) pressure.
Obviously, my aim is to not get to this point but I'd like a warning system nonetheless.
Ta,
Tim

I don't think that'll work. As there's no restriction after the lift pump and fuel is free to flow back to the tank then there's
no/little presure in the line... I think...

That was my fear.

Put a restriction in the return line?

Can’t you put a float switch in the side of the tank so it puts a light on the dash

Whats the weight of the fluid in the swirl pot? If you have a non return valve prior to the pot and then the pressure switch between the non return
and the pot that may work (i'm guessing). eg
Pump -> non return valve -> pressure switch -> Pot full of fuel
