Jensen-Healey Fuel Tank Questions

Hurricane Michael put a big kink in operations here in the Florida Panhandle.
We are finally at a point where work has resumed on the J-H project.
We have three fuel tanks and hope to get one good one from the bunch.
The candidate has been red-coated, but the four little tubes near the top fitting have us puzzled.
They are plugged with the red-coat. What is their purpose? Do we need to clear them?
We won't be reinstalling the charcoal canister or the vapor return line.
Regards, Ray
 
If all the vapor and return will not be used, the only one that counts is the pickup, but you may want a vent to the charcoal filter to prevent creating a vacuum in the tank.

Just hunted down my J-H shop manual, it's Spartan with regard to details of the tank and those tubes. No illustration, either.
 
|Dr,
Thank you! Since posting my question, we found two other fuel tanks with the pile-o-stuff. One had the pickup and gauge sender which are in good condition. Seeing that for the first time answered many questions. We will take the vent from the top with a hose down through the floor to avoid the vacuum.
Thank you!
Regards, Ray
 
You're welcome, Ray.

May I suggest you use that charcoal filter, relocate it to the rear as high as possible and route the vent line thru it.
 
We have a couple of those charcoal gadgets. I will see where we can mount one. Thank you again!
Right now Bill is wrestling with the wiring.
I have discovered you must connect the clutch and throttle cables to the pedals BEFORE the pedal box goes into the fire wall.

My sympathies, Ray. Those 'lessons' become hard-won experience. And why it costs so much (in both time and money) to really restore old Eurotrash. No matter the make/model, there's always a learning curve with the first one you encounter.

One of our old shop jokes is: "If ya ain't done it three times, ya ain't done it at all!" :wink:
 
Dr. E,
Another garage joke about English cars is drive it for one hour and work on it for four!
That was back in the '60's and '70s' when those cars were still relatively new.
Now-a-days, it is work on it for years, then trailer it to a show and hope it starts!(grin)
 
hehee!

When I tell folks I drove the Elan S-3 for eleven years as my primary transportation, those who are familiar with English lumps of the era stare at me as if I've three heads... But it's true.

Same with this MGB. From '88 to '98 it did 100 mile round trips daily for work.
 
When I was a mechanic I remember a couple of cars that seemed to spend more time in the shop with me then they did on the road. Once one issue was sorted a new one would pop up.

When I was a kid my dad rode a Moto Guzzi and a couple of old bikers lived next door, both rode old Harleys, one a pan head and one a shovel head. My dad would drool over those old bikes and once he admitted his admiration to one of the fellas, the reply was that they both admired his Goose. When my dad asked why they said that while they wrenched on their bikes nearly daily he would walk out to his hit the starter button and without fail ride off every day.
 
Dr. E,
We have managed to swap the wiring harness from one car to the other. We are puzzled by a small 2-prong connector that is behind the seats in the bulkhead high up. Any ideas as to what that is? We can't find it on the schematic. Could it be something just for US cars?
Regards, Ray
 
Ray, could it be that someone had at one time added a third brake light?

trunk light?
 
Both the parts car and the car we are rebuilding have it. It comes from the trunk harness and goes to the bulkhead and accepts a two prong plug from the passenger compartment. So, trunk light is right out as well as an additional brake light.
We have three soft tops and non have any electrical components.
So, it is still a mystery!
Regards, Ray
 
See if you can't find a catalog or brochure showing all the options you could order on a JH. If both have it I'm willing to bet it was for a factory accessory of some sorts.

I was thinking the same - perhaps interior lights for a hardtop?

I think it may be for the defroster on the factory hard top.
 
That or a courtesy lamp for the area behind seats? Can you tell what the wires' color codes are?
