The NSI sump tank has a holly float mechanism between the

incoming

fuel

line

and the tank. The incoming fuel boost pumps are switched by

a

low

level

switch on
the sump tank and fuel flow shut off by the float on the

tank.

Fuel

does

not

seem to
heat up at all.

Does the plane in question have EFI?  If not, what is the value

of

this

observation?

Tracy

Hey Tracy,

    Yes they do use EFI. All stock Subaru on the engine as far as I

can

see.

John Gibbons

OK, thanks John.  There is no doubt that a sump tank can be made to work

and

it might be the right answer in some situations.
  I am amazed that NSI and Eggenfeller both use the stock Subaru ECU.

Tracy

Tracy,

    I thought that last post might be confusing right after I hit the send
button. The stock Subaru parts I was refering to was the engine components,
injectors, rails etc. Sorry for the confusion.
