tank fuel pickup/sender

Doug,

Check the next to the last post in this link.

Thanks for that link John.

I'll look at mine again but on my new pick up the internal pick up is at about a 20 degree angle to the right from the exposed tube.

Therefore if you look at that picture the internal tube and float would be heading into the left exhaust manifold.

I have to reserve judgement for other pictures. Hopefully some will take the effort to pull the cover off of the tank and snap a picture?

Hopefully there is not more than one version of the pickup.

I can't possibly orient my pickup like that one.

FWIW, the combination aftermarket sender that I have (on the shelf) is oriented so that if the hose tube is pointing toward the engine and is perpendicular to the center line of the car, then the fuel pick up and the float arm would be pointing toward the rear of the car, and they would be parallel to the center line of the car (give or take a degree).

This sounds like what you have.

John

No. Not at all.

Let's say that the front rear axis of the car is 12 to the front and 6 to the rear.

The pickup tube now seems to be at roughly 6 and the hose connection tube is roughly at 7.


This is a brand new assembly from Wilkinson. How accurate this is to an original late L, I have no way of knowing.

At this moment it appears that I have it working. It's showing less than 1/4 tank on roughly 4 gallons so I'm a little skeptical that everything is finalized.

The float is made of hard black foam that pivots on the lever arm.

Chances are that the pickup assembly is the last version from the Euro cars rather than the US version so I suspect that I'd have to figure this out myself anyway.

Doug,

Does this help?

Possibly but who is to say that all the interior baffling on the tanks is the same?

I wouldn't presume so at all. Especially on the last Euro versions of which this pickup/sender is probably from?

Incidentally, does anyone know the official capacity of these tanks? I can't find that listing anywhere?

Thanks everyone but this looks like I am on my own on this issue of orientation. Seems like I have it right at the moment but who knows if it will read full, when full in this position?

Just another quirk to these cars.

It's listed in my blue ('71) owner's manual as 21 US gallons. While driving around the other day, I put in 19.6 gallons, so it's close.

You can adjust the fuel tank gauge reading by removing the sender and bending the long arm up or down slightly. This is an iterative process but if you've removed the glass from the left side rear quarter window, it's a 5 minute deal to pull & replace the sender with tank in car.
When adjusting, do NOT strain the right-angle bend going into the plastic resistor box- the arm wire is pretty stiff and will crack there if worked much. When I alter senders for in-tank electric pumps or increase their ID for larger capacity engines (stock fuel-out line diameters power-limit an engine to about 400 bhp), they always need adjusting for the car they'll be used in.

BTW, the red 'low-fuel' light in the gauge comes on at about 2-gallons-to-empty when things are adjusted correctly. On a good-running 351-C, that gives around a 30 mile range to find a station you like. Finally, if preferred, your old brass float if in good condition will fit the new sender. But hollow brass floats can leak while the black nitrophyl foam never does (in regular gas; lg. amounts of alcohol is another story).

I'm wondering if it was bent or I bent it when I installed it. 4 gallons should show more that 1/8 of a tank?
