Float chamber issue SU Carb


Recommended Posts

That doesn't look like the original tube, it appears to be copper not brass like the other two so perhaps it has failed before? 

JB-Weld will hold it if you clean both mating surfaces well, back to bright metal.   Don't use ordinary epoxy as that isn't fuel-proof.

You  have to get  the right loctite as only a few are fuel-proof Andrew, and fixing to aluminium alloy needs an appropriate primer.  JB-weld is easier to get hold of.

The identical thing happened to me first time out with one of my brand new SUs in my '6.  Being in a hurry I glued it back in with Araldite, and set off on a 60 mile journey.  Its done around 15,000 miles since and the araldite is still holding, but you have reminded me that I should do a more "permanent" fix.

This was a problem 50 years ago on the Ford V6 Essex engine carb.  
The tube pulled out and the fuel pumped all over the engine.   Fix I think was refit the tube with araldite  and drill and pin one side of the tube in place from the side.

Epoxy adhesives, including JB-Weld, have excellent compatibility with petrol (including alcohol mixes). When cleaning back to bright metal ensure you have a rough finish to get good keying

Yep! - ask me how I know?

Looks like a PO couldn't get hold of the proper float chamber lid and used this as a stopgap. Yep...ordinary epoxy isn't fuel-proof. Tried this method prior to posting. Used a 1/4 tank of fuel to get home when it failed miserably.
