I made it 20 miles South to Coos Bay Oregon got a new set of plug wires
changed fuel filter in front of carb, new coil, bought new distributor
cap but didn't seem to fit right going to store tomorrow to try another
ignition module I can do 55 but have to keep my foot in it on any Hill. my
brother bought me a new set of plugs but they missed on the cross reference
can't seem to find the right plugs the old ones don't look too bad.
Someone asked what was going on before this happened I actually had gone up
some long grades Towing my tracker.
The next morning something didn't seem right but drove 60 miles or so to a
campground stayed a few days then hit the road this morning and filled up
with gas that's when things got worse.
May have to limp back to San Jose will be calling Jim K again.

G'day,
Assuming that you don't have a way of checking the fuel pump output pressure I'd change it. They're not expensive and they're easy
to change. Plus if you buy one now the diaphragm will be compatible with ethanol fuel. You need one for a Toronado WITHOUT Air
Conditioning.
When you change it I'd suggest you install a metal fuel filter here:

I would do like Rob suggested and also put the Fuel selector to the other
tank.
The origional selector switch are know to be deteriorated after 45 years
and need to be replaced.
Also see if there are other filters in the line towards the rear by the
tank.

Agreed with the others. You probably got some bad gas or stirred the sludge
in the tanks and plugged some stuff up. Check all fuel delivery stuff. I
know that many here do not like the fire risk of a fuel pressure gauge but
I was able to diagnose a similar issue with my fi 77 thanks to a p.o.
installed fuel pressure gauge at the throttle body ( bad power connection
at fuel pump wiring)
To isolate ( and clear or blame) the fuel selector valve pick either
incoming fuel line and bypass the valve ( plug the other tank outlet hose
to selector) and try running that way. If it runs worse the problem is
likely between there and the tank pickup. then switch to the other tank
feed and see if that resolves the issue. a package of crimping plastic hose
blockers ( any auto parts store)works well to quickly temp close the feed
hose from the isolated tank. You were pulling grades towing right before so
a lot of fuel was being pulled through. My bet is fuel delivery obstruction
or pump system.
Good luck

I had a problem like yours one time and found that the carburetor had some junk in it. I had to take the top (the "air horn") off the top of the carb and clean it out. It does not take any fancy tools except a camera to document every step so you can put it back together the right way. Not hard and will only take a couple of hours maximum.
