Gas tank vent...maybe

[mtruckr]

On a '66 Suburban... quit running, but will run on starter fluid.
Maybe a fuel pump failed... put in another one that I would bet money was good (famous last words), no luck.

Old skool assistant says pump prob doesnt work (no ability to generate suction with thumb covering intake pipe)... and a new one for $22 ain't no big deal...

However, tried to add fuel to tank (it was kinda low and mightve been part of the problem, but I doubt it)... and found that fuel was hesitant to go down the filler neck. (was NOT using a long funnel or gas nozzle... was spoon-feeding it from small available gascans and water jugs).

So the question is... anybody ever has a vent hose get blocked and generate these same issues?

I don't figure 47 year old rubber hoses last forever, and I don't imagine it would be too tough to find/remove/replace... but just like to get input before diving in.

Thanks for ideas and experiences
