: I think I'd get an estimate for fabricating a
: "standard" fuel rail first. You
: may find that it's not much more expensive
: than paying someone to do all that plumbing.
: Rance FI charges $40 an hour for fabricating
: and I'll bet he can do a fuel rail alone in
: a relatively short amount of time. Also, I
: wouldn't force fuel down your vent tube.
: That defeats the purpose of a vent! Doug is
: investigating methods of fabricating a fuel
: rail. Maybe you can get some preliminary
: tips from him.

: I have done a few serious research trips to the
: junkyards and found a numbr of different
: fuel rails which are good candidates for
: modification into our SL6 rail(s).
:
: The one that seems to be the closest is off a 6
: cylinder BMW, it is the one that is trapped
: under the intake runners. (just our luck)
: This rail is set-up on the needed 4 inch
: centers. What I did is cut 2 inches out of
: the center to get the shorter SL6 spacing
: needed at the center position. ( I brazed it
: back together using an inner support
: "sleeve" to position everything
: and add stiffness).
:
: Trouble with this rail is it is a "hose
: clamp" type which uses short pieces if
: hose between the rail "barbs" and
: the injectors, it does work and is pretty
: easy to make. As Bob noted, the extra cost
: to just have an o-ring type rail made-up may
: not be that much more then the time and
: effort to do the junkyard re-fab rail I did.

: I think the issue here is money. However, in
: my opinion money spent on a good safe fuel
: rail is money well spent. A leak here with
: EFI working fuel pressures could be
: catastrophic.
