MG MGA - carb to carb hose

I feel a little stupid asking this question, but its been a long time since I did any work on the carb to carb hose, and I didn't find my answer on Barney's site. Is the brass fitting at the end of the hose that attaches to the front carb part of the hose? I can't remove the hose from that bit, the hose end just rotates.

Thanks, George

What hose?
Art Pearse

I assume that it is the fuel supply hose.
Is that correct?

The fitting has a hose barb. The hose is secured with a crimp ferrel. If the hose is bad cut the crimp fitting to remove the hose, ans you can re-use the end fittings.

George, The nut on the end of the hose will rotate freely of course but the pipe into the hose should be fixed or else it may leak petrol.
I bought two new hoses during my restoration but they were both incorrect. The diameter of the carb-carb hose was too big and the pipe-carb hose was too long. Over the years I've seen many pictures where the pipe-carb hose looped up excessively because they were too long.
So I decided to make my own and bought a metre length of steel braided nitrile hose with 1/2" OD and 1/4" ID. I made the carb-carb hose 15.75" end to end (including fittings) and the pipe-carb hose 11.5" long.
Getting hold of brass ferrules was not easy so I made them up from copper end feed reducers 15-10mm. These are easy to get from plumbers shops over here and they are cheap at around 20p each. You have to trim the 10mm end a bit, hammer it flat and then file the correct diameter hole.
To do the crimping I modified a copper tube cutter by removing the cutter blade and replacing it with a 1/8" thick disc. I made two crimps on each 'ferrule' - see pic.
If you still have the original yellow petro-flex bands on the old hoses you can move these to the new hoses. Using a hair dryer you can soften them to get them off and heat shrink them back on the new hoses. I was surprised they had heat shrinkable plastic back in those days. ..........................Mike

Nice job Mike. I cheated and used rubber hose and screw clamps over the old fittings.
