We are unsuccessfully trying to reconnected the fuel line (from fuel
pump to carb) back into the carb. It just doesn't screw in.
Is there a trick on how to do this?

Alignment is critical on these fittings. They MUST start in the threads by hand/fingers or they will crossthread and strip. If you can make the other end of the line free to move then it will be so much easier to get the one you're working on started. Try loosening the nut on the other end of the line to get some freedom of movement, but don't remove the line from the other end. These things always get me on steering racks, but I rarely have a hard time on the carbs.

Terry,
thanks for the idea. The full story here is:
The 23 footer's fuel line from pump to carb had some Previous Owner
amendment which needed to be removed because fuel was spraying out.
Removal worked, however the new line didn't come on time. Now the idea
of my buddy was, to remove the fuel line from the 26' and put it into
the 23' - however, the fuel line doesn't want to get loose on the fuel
pump side. In the meantime we butchered up a temp fix for the fuel line
in the 23' and now will use the original 23' fuel line back in the 23',
but the 26' fuel line needs to be reconnected to the carb.
This so sucks, as I have to be in Baltimore with the 23' by Friday
midday to get it shipped to Europe.
If anyone wants to lend a hand, we are currently in Scottsville, VA -
another name for this area is: Middle of nowhere...

Tighten carefully, the fitting is fine and 'soft.' You can ruin the carb fitting in an instant. Flare wrench is nice, but not necessary.
There is a 'repair' kit available for 'oops.'

Well, my buddy had success, and the fuel line is back in - at the cost
of an old brittle T-piece connecting three small vacuum lines. We will
get a replacement in the morning, and report back about the success of
the operation.
Maybe anyone know about the OD and ID of these small vacuum hose T-piece
connectors?!
Thank you all for your hints!

thanks for the info. I'll keep it in mind, although a nice torque wrench
has been on my list for a long time :grin:
For now, it looks okay. The morning will tell how good or bad the
tightening of the fuel line went. Wish us luck.

Terry,
These simple techniques can save lot of time and screwups.
Your suggestion should be heeded by lot.
I respect you for attaining your Master Tech ASE Certification. I just have
the Engine Tech ASE Certification.

Is there a safe way to get a fuel pressure gauge taped into this line?
Is there a better way to get fuel pressure?
Does anyone have an electric fuel pressure gauge solution?

Thank you, Ken
Is changing to an EBL/EFI system worth the cost for an average user? Do you
get a significant mileage gain?

John,
We sell all types of EFI, but only the Howell based unit with the EBL
system will get you 1-2 mpg and better power . We have the most updated bin
installed so it will do like I say. Some ended up with some other in and we
later had to help them.Plus we have people that can help analyze the unit
should ever have any issues.

Owning a Gmc is not cost efficient, not no way, not nohow. So, anything
you do to it, automatically joins into that fray. If you want to convert to
fuel injection, do it for reasons OTHER than economic ones. J.M.H.O..

If anyone is looking for a replacement pump-to-carb fuel line, Inline tube makes a reproduction part for a '73-'76 Olds cutlass that should work;
https://docs.wixstatic.com/ugd/4d7af2_9dac1b92b352467ab9d76476103e76ce.pdf
They also make a similar part for '77 cutlass with 403.
Fortunately our GMCs share a few parts with the desirable classic car world.
One caveat; The plane of the carb flange is angled slightly differently on rwd vs fwd Olds engines, due to the position of the engine as installed in the vehicle. Rwd Olds v8s, like most rwd v8s, position the engine with the crankshaft axis dipping toward the trans and rear axle for alignment, while the Toronado has the crankshaft axis more parallel to the ground. They designed each intake manifold to place the carb parallel to the ground for proper float level orientation. The carb mounting flange tips "forward" on a rwd manifold, and relatively "rearward" on Toronado. This angularity would make a very slight difference in the fuel line as well, but I suspect it could be made to work by tightening the carb last. Inline tube also offers a '67 Toronado fuel line that might be closer to our original part...for $25 this should beat trying to bend something from scratch.
