This!
Exactly the same thing that happened on my 1994. I replaced the air intake tube and all was fixed. The air intake is likely torn in the corrugated section.
The time mine failed smog, passed everything except for the vacuum test, all I replaced was the EGR Vacuum Modulator. Then retested for free and passed with flying colors.
I picked up 4 Scepter water cans two weeks ago from Lowes. I searched inventory at stores around my area to find the ones that still had them in stock. Only people in the know will know they're discounted. At the store they're all still labeled at the original $55 price for some apparent reason...
Way back in the days before I got scuba certified, scuba tanks had J-valves that would close airflow when tank pressure dipped below 500 psi. Flip knob to reserve to use remaining air to return to surface. This was in the days before reliable submersible pressure gauges.
DS Tactical is where I ordered my Scepter Fuel Cans before the States banned the sales of them in 2009 because they are not CARB compliant or child proof. Yet the US Military uses them and can purchase Scepter Fuel Cans new.
I use white gas when I'm mountaineering in winter conditions. I consider white gas relatively cheap in cost. But that's probably because I'm comparing it to the expensive backpacking canisters with Lindal valves.
I typically use just under 2.0 lbs of propane for a 9 day trip: hot breakfast...
I hear you. I want a 5lb propane tank for compactness, but they cost more than a 20lb one. So I end up sticking with the Coleman-style 1lb disposables.
