canister purge solenoid BBQ??
'93 LT1. I removed both hoses on the canister purge solenoid located on the right side of the intake manifold near the throttle body. They are both old and brittle.
1) Can the the small 4" hose that curves be purchased anywhere? It is 1/4" i.d. on the solenoid side and about 3/8" i.d on the throttle body side.
2) Removed the old 2' long hose 1/4" i.d. hose that goes from the purge solenoid to the plastic vacuum tube below the coolant tank. PROBLEM: I tilted the hose to look at the condition and about a teaspoon of what looks like tiny crumbs of black charcoal poured out. This must have been sucked out of the EVAC canister? From those with experience, now what could be the cause and solution.
Car runs fine, no check engine lights.

I pulled out the vapor canister and it is leaking charcoal out of both the inlet and outlet vacuum ports pretty badly. The purge solenoid valve located next to the intake manifold also had charcoal bits in it. I tested the solenoid and it is not functioning. Surprisingly there is/was no check engine light on. At least the ports on the purge solenoid valve are small and kept most of the black charcoal pebbles out of the throttle body (where the vacuum is delivered) and sucked into the engine cylinders.
Now i know why when removing the gas cap there was so MUCH gasoline pressure vapor released . The vapors had no place to vent due to the vacuum lines being clogged.
I ordered a new canister, purge valve and purge valve solenoid from Autozone, lifetime warranty on all of it. I am recording the repair for another fun project video on my Youtube Channel Ozzstar.

I changed my canister and valves on my 87 and it ran better. It was screwing up my vac and I think the computer was compensating for this. Stopped having the gas fume smell and high pressure at fuel cap. There is a small hose close to fuel tank that can leak fumes if it is bad. Good luck
