<div style="color:black;font: 10pt arial;">Thanks Dave and Jeff.
<div>I think that while the vent line may be partially blocked, it is sufficiently open to pass vapor and fuel. I think that Jeff may have hit on the problem being the anit-run on valve. I was working on the fuel system, I think that I have inadvertently knocked a couple of connections off of the oil pressure sending unit. My gauge registers oil pressure properly, and that wire was not disconnected. However, if I put the two wires back on one way, the oil pressure warning light comes on and stays on. This is clearly wrong, so I reversed the wires. I cannot tell if the anti-run on valve is now working properly. I did note that when one of the wires accidently touched the oil pressure wire, I saw a spark and clearly heard a click at the anti-run on valve solenoid. However, when I connected the wire to the other post on the sending unit, I could not hear a click when cranking or shutting down the engine. I have looked through my Haynes manual, but don't see a diagnostic procedure and the only wiring diagram I have is for a RHD PI unit. Mine is LHD carbureted. Any advice as to how to verify the correct wiring for the anti-run on valve?</div>

My problem turned out to be the vinyl hose leading from the trunk area to the engine bar had sagged down and contacted the exhaust system and melted shut.</font></div>

<div><font size="3">Make sure your system is per design and not missing something. There is typically a liquid/vapor separator near the tank. If that was bypassed you will get liquid fuel where it shouldn't be.</font><br clear="none">

<div dir="ltr">> I just replaced the fuel tank in my 1976 TR6 and after a short drive, I noticed a leak coming from the vent connection on top of the tank. I tightened the nut on the connection, but don't really understand why there would be gas in the vent line. I also noticed that when I opened the fuel cap, there was a hiss like a suction. I feel that either the vent line, which seems open when I blow air through it from the cannister attachment or the carb bowls (ZS 175s) may be too full and there is a vacuum that is pulling fuel out of the bowls. My TR6 does run rich. I don't understand why there would be a vacuum in the tank. Also, I noticed a bit of oil around the oil fill cap which I have never seen before. I checked the oil and the level seems correct. I thought I smelled a bit of gas in it, but that may have been a bit of imagination on my part. Any suggestions would be appreciated.<br clear="none">
