I usually associate an air leak in the supply lines with a lot cranking at start-up time. I bought a '76 300D once from a guy who tore down the engine because of a hard starting. I bought it for the rust-free body. Transferred the factory re-man engine from my rusting body into this one, and instantly had a hard-to-start car. I found a small rubbed hole where the fuel line came up into the engine compartment. Fixed it with a splice of fuel tubing, and it started instantly.
Now, a collapsing tank would be a real pain. I usually fill when the gauge gets to half - so don't really have an indication of how much it holds today. The tank is at half now - when this last incident occurred. I think I'll start with the vent system.
