Paul and Russell,
Keep going you chaps, you've almost got it !!

A suggestion, there seems too many complex bends.

It might be better to minimize the bends to two 90 degree bends each

tube.

I don't know if this will fit Paul - how about a 90 degree bend coming

out

and bending forward, on each tube.

Both tubes turning up or down into a  horizontal plenum - preferably
injectors facing down.
The inlet tube coming from the front directly into the plenum ( same

as

original plenum).
Will it fit ?

I don't follow you. Can you do a 3D using stock bends? A sketch?
Both tubes have to be equal length. 20 to 23 inches long.

George, does not look too promising.

I added a couple of 30 degree bends to lower it a bit.

Paul

Thanks for that rendition Paul,
I agree with your assumptions  after thinking about it further myself.
Also your point in dribbling fuel into the inlet - I didn't realise the
problems.

How about turning that plenum and injectors toward that area near the PSRU,
where there is a little extra room.
Thanks again for the effort.

I tried this and it works better. Minor problem with one fuel rail
but that can be angled down on the intake pipe. Can't go sideways as
that would get into Tracy's PSRU plate or the bell housing.

the P-ports give a lot more flexibility with tuned manifolds.

There are four 90's and two 45 degree bends.
