My gas tank has TWO lines running from it. The top line runs up the driver's side and goes into the carburetor. Obviously this is the main gas supply. (also, it has an electric fuel pump hidden back by the gas tank.)
Now -- here's the mystery. My gas tank has a SECOND line which comes out of the gas tank at about halfways up the tank. It runs up the passenger side. Today I traced it and it goes.... (are you ready for this?)... into the oil line!!!>!?!?#$?@!?!##

Can anybody give me a reason why this is there?
Wild guess - wonder if it was part of an oil dilution system to reduce oil viscosity in extremely cold conditions? This was used on some aircraft engines operating in very cold areas. Some fuel was mixed with the oil in the crankcase before shutting the engine down to thin the oil and make cranking easier on the next cold start. The fuel mixed in with in the oil would evaporate from the crankcase as the engine warmed up.
Yes the line comes up to the engine compartment and then connects to the pump. But it does so using a TEE which also goes to the oil lines.... at least that's what I think it does.
Here's a picture. The gas line is coming up from the bottom into the TEE fitting. So.... what prevents oil from leaking back into the gas line?
Well, it wouldn't surprise me to find that "someone" re-engineered parts of this system.
While it does have an electric gas pump on it, that makes me a tad nervous since it would create even more vacuum inside the gas tank. So the dash pump shouldn't be needed at all.
Is that an oil pump on the side of engine in the above photo?
I'm ready to add some Neatsfoot oil to the clutch. After 9 screws removed, and a rod and cotter key, I'm still 3 or 5 screws from removing the upper floor board.
So, I took a break and crawled UNDER the car. Dang it. It appears that I can easily get to both clutch "holes" from below.
So my question now is - what's the easiest way to oil it? Squirt bottle? Some sort of spray thing-a-ma-jig? I ASSUME that all of you blokes religiously oil your cones?
Well... my wife remembered that I got a hypodermic needle from my dentist a few years ago that I never used. (He gave it to me withOUT a needle. I thought that I was going to use it to squirt glue up under my running board mats... but then I changed my mind.)
So, I looked and found it. Turns out that it works perfectly to "capture" a measured amount of Neatsfoot Oil, and then it fits perfectly into the two holes on the flywheel. So -- problem solved.
NEW ISSUE: The gas linkage to the pedal sure comes close to the flywheel. Here are three photos showing that. It's a little unnerving to me, that the flywheel would be spinning so rapidly, so close, to the clevis. It's less than the thickness of my finger.
As long as the gas linkage is not loose enough to get nearer the flywheel you should not be afraid. Check (when the engine is not running) that the space is enough (not touching) even when you "pull" the lever towards the teeth of the flywheel. I have only 10 mm space between the flexi hose and the flywheel on Solan, which should be enough.
And I think your finger is a little more than 10 mm, Bill???

Great video, Bill, congrats with first start. Regarding the fuel system, I think it has been modified by someone. I assume an electric fuel pump has been added when the hand pump operated pressure system failed. The T-Connection to the oil line is a mystery. I'll check the connections on my H-4. The component on the pressure line below the T could be the non-return valve that keeps tank pressurised after applying the hand pump.
Yes the line comes up to the engine compartment and then connects to the pump. But it does so using a TEE which also goes to the oil lines.... at least that's what I think it does.

In my H-4 the valve pushrod operated pump behind the distributor is disconnected from the air pump line. I took the pump out to try to find out how it worked. The piston was also removed by somebody at some time, and its only function now is being pushrod guide. Could this pump be an air pump installed with the purpose to maintain the overpressure in the gas tank, eliminating the need to apply the hand pump when driving?
