Researched for answer in the threads but could not find info/answers I was looking for, so below is what I am planning for-
Its a LX, 5 litre EFI from a VS commodore, 400hp max, street car
Originally i was going to use a 120ltr BD drop tank with a VZ in tank mra (tall unit)
This has now changed to using a 90 ltr BD drop tank which now means I will use the VE MRA (Short unit)
The VE MRA has one only outlet, internal reg and pot.
The tank has 3 breathers (1/4 or 5/16) located high at frt of tank.
Tank also has original fuel pick up boss to which i will fit the pick up/level sender unit. This will be my fuel return.
My intention is to use standard LX fuel line from MRA outlet to inline filter to VS fuel rail.
Exit fuel rail via the standard reg (vacuum type) and return via same size fuel line to the original fuel pick up barb on the tank.
The three breathers on the tank will be plumbed to the original vapour separator (bottom barbs), the output of the separator (top barb) will go to the charcoal canister. Then from canister to engine manifold/TB.
The fuel tank cap will be VZ type. So will the fill tube. I will also plumb the filler breather to a suitable (same size barb as on filler tube) fitting on top of tank. This fitting should be a anti rollover type (allows air out of tank when upright and seals passage if inverted)
Have I missed something? Is there anything that will not work as intended? I want to cover all bases now before the tank is made should i require any mods.
Let me know what you gurus think.
Thanks in advance, Hatch
