type of bolts used on a Mk2 fuel sender

[Lynn Eades]

And on page 204 it says it again for the fuel sender screws,10-32, but then it also says for the "Cap and tube outlet", Screw # 2BA x 3/8 round head qty 4.

Isn't that Irish, to have two different, but visibly indistinguishable standards melded together in one fuel tank.

How stupid of me to think they would be the same!

It must of been engineered by two different engineers

[Stew Robertson]

no matter what size, the 10 /32 will work, as by the time the thread is cleaned with a 10/32 tap the screw will have enough pull to hold and seal
But that is just my opinion /millwright for the last 50yrars/Fixer of engineers mistakes

Agreed: the filler neck is original British, so would be British threads. The sending unit flange is a Cdn design, so would be North American threads. Makes perfect sense.

We have used 10/32 on many tanks with good sealing and no thread issues.

[Richard Farrant]

As the British design only used dipsticks in petrol tanks, the addition of the sender units in the Canadian design, would obviously use hardware and tooling that they had to hand in their country. As much as possible was kept interchangeable.
I have come across differences in the axle pinion shafts though, the threaded hole in the end of the pinion shaft, I have found with both NF and NC threads, anyone come across that?

[Lynn Eades]

Richard, the tooling was in use in Canada for the making of the previous 40, 000+? (number unknown to me) carrier fuel tanks, without senders.

The fuel tank sender, and the fuel pick up both have a Ford of Canada part number.
The pick up mounting ring has a TL (Brit?) part number. Maybe this is the problem. (they too would have been made by Ford of Canada)

On the Pinions, yes I have seen both. The fine thread seems more logical to me. I have wondered if the difference was the origin. Brit, Can. or US?
The small pinion bearing was different between U.K. and Can. production.

I just got in new sender units from Macs' Auto. Comes with new screws and gaskets. So, looks like the bit of drilling and re-tapping will be in SAE.

The Fuel pick-up uses BA then? OK, I have taps for that...

Thanks everyone for responding!

Oh, while I didn't find the extension for the distributor, I did find one in the box of spare distributor parts that came with the carrier. Will be putting it allon this weekend.

Also got in a new Fuel pump so I may already be prepared for a dead fuel pump gasket from sitting so long.

I did a pretty good search under the engine with hands and a reach magnet, with no luck, I had just vaccumed the inside of the hull pretty thoroughly only a few days before this.

A few nuts and bolts and two live .38 S&W bullets with bad primers!

Oh, a rebuild plate on the front right side of the engine says it was rebuilt in 48. More details to follow for those that are interested!

Again, everyone! Thanks for your help!!
