I need the fuel diagram for a 91-94 samurai

You need to design & fabricate whatever
suits you, anyway you feel it looks good,
works & is safe

No one can tell you how to do a custom fab

I wouldn't want someone to tell me how to
design & fabricate something, after 45 years
of doing it

91 olds cutlass supreme runs rough and wont stay idle.

If your vehicle is fuel injected I would say you have a blown fuel regulator. This would cause excess fuel into the cylinders (flooding) causing a miss and coughing and also blow fuel into the air breather. If will also cause the vehicle to run poorly and could cause the vehicle to stall. Also to much fuel on startup can flood the cylinders and cause the vehicle to no start.

My 91 GMC Tracker sometimes won't start and other times starts just fine. It also shuts off randomly.

i daily driver, or just took out of a barn for winter duty.?
context? when did it run right last, 1day, 1week or 1 year.ago.?
sounds Canada , nobody ever posts location, and guess what
canada is not texas. 85F today here. and all week.
fuel antifreeze is just methanol. it works,

stalls, are complex.
so are won't start.
the EGR sticks open on most , its a 50k service point and is never done by most owners. and fails like clockwork.
first use test fuel, does test fuel work , when it wont start.?

did you read the spark plug tips to see if its flooding or starving for fuel.
did you do the fall tuneup. make sure spark is good?
really fast starter,, that is odd.
so your saying it always starts eventually but not always
and when it does run, its with full power on hills, etc?
Id do the 60k tune up on it.
see it here.

if it wont start, try the op guide rule,crank WOT (unflood mode)
wide open throttle, this cuts all fuel injection and clears all floods.
if not flooded and spark is good (tuneup) and new fuel filter.
then try test fuel. on a good engine and good spark engine.
I remove a intake hose, and spray it in there.
and crank , does it start now, for at least the life of the test fuel>
