1/8" Gas/BSP fittings

We are trying to fix a few niggles on an old Onan water-cooled generator, and one of the last jobs is sorting out the drain tap.
When we got it, there was a bolt stuffed up inside the radiator drain tube extension, but it should have a drain tap in there.
Have cleaned the thread out, surprisingly it was 1/8" Gas, not an NPT thread, but we now need either a drain tap with a long body so it clears the cowling, or an extension tube and drain tap to suit.
Has anyone got anything that would do the job or could be modified?
The drain tube need to be male/female and 1.25" long, drain tap can be either a modern type or an older one with lever.

Go to BSS and get a long barrel nipple,or an 1/8" coupling and a bit of 1/8" nippling tube.This would let the coupling screw up against the casting and look nicer than a hex or barrel nipple and coupling. Mark

Thanks for the suggestions, very helpful as always.
I did pick up an assortment of extension pieces and a small lever tap, but eventually had to take the whole radiator off the engine, including its cast shround, to get at the drain tube which is 5" long and screwed into the base of the rad.
Once I could get at that, I could see what the problem was. Over the years, various bolts had been screwed into where the tap should have been, and the thread had just rusted out, leaving a hole that was just about small enough to let a 3/8" bolt grip.
That last piece was actually separate, and I was able to unscrew the remnants, make up a longer brass spacer on the lathe, having blagged a bit of brass hex from our landlord. Drilled through and tapped each end, Screwed the new tap in and job done!
Took longer to clean the sludge out of the bottom of the radiator than sort out the drain tap....
