Hello,
I found these N40SH's w/ 12,800 gauss. Curved w/ opposite N-S orientation. I
will have to cut the steel fuel line and add rubber fuel line.
If these are good for the fuel line how will I be able to tell which end has
the decreasing strength? At least I can't get the N-S wrong. LOL.
I would like to add some to the air intake also, to orient the air opositely. I
don't think these would work too well there. Worth a shot?

I appreciate any help. I already have 2 Smacks boosters installed and run
acetone and (trying) xylene on my '79 Chevy Silverado 305 2 barrel.
On a good day I get about 21 mpg highway (11 mpg originally).
Thanks for the help!

Peace,
Brad
