OIL FEED LINE T100 ROCKER BOX - Replaces 70-3805 (UK LFH)
Oil feed line supplying the rocker box on the Triumph T100, replaces the earlier 70-3805 part number.
This is the oil feed line that carries oil up to the rocker box on the Triumph T100 cylinder head. It runs from the timing chest or oil tank area up the side of the engine and feeds the rocker gear so the top end gets lubrication where it needs it. Without it, or with one that's cracked or crimped, the top end will starve for oil in short order.

The part number 70-7576 replaces the earlier 70-3805, so if your parts book or an old invoice lists 70-3805 you're looking at the same physical pipe under an older number. It shows up in the OIL TANK section of the parts books and has appeared across catalog listings from 1968 through 1973.
These pipes tend to get kinked or dinged up over the years from being removed and reinstalled, so if yours doesn't look straight and true anymore, it's worth swapping in a fresh one rather than fighting a bad bend.
