Earlier this year I replaced the fuel pump on my TR6. A PO had stripped the threads on the input side of the OEM Delco pump causing a slight leak. I sourced TRF’s Italian-made pump because I liked the idea of being able to rebuild it. (I’m 70, so it will be something to keep me busy in my 90s.) I used a new nut for the input pipe and new compression sleeves on both pipes, but reused the nut on the output pipe since that side wasn’t leaking. Bad idea: no more leak at input pipe, but output connection now leaked! Ordered a replacement nut from TRF (part # T26S15G13), and it turns out the new part has a 3/32” protrusion beyond where the threads stop. The old part is cut off where the threads stop and was apparently not long enough to crimp the compression sleeve. Lesson here is to always buy new nuts from the pump supplier when installing a new pump.

Interesting! They finally made a nut that works. BTW, T26S15G13 is not a TRF part number, but their database code to indicate that the part fits (some) TR2 through TR6, Spitfire Mk 1 through 1500 and GT6 Mk 1 through 3.

Hi Randall,
Perhaps TRF designed a one-size-fits-all nut. I learned, while researching my problem, that it's hard for owners of TR3s and 4s to find replacement nuts and sleeves for their cars. One guy found a source for longer nuts, but paid $35. TRF nut is < $10!
