Jaguar triple carb fuel feed pipes.

[a8hex]

My XK150's engine is somewhat of a mishmash, it's a 4.2 from a SeriesII XJ (I think), with a Mk10 inlet manifold and carbs modified to be like an E-Type's. Now my question is about fuel feed pipes. Does anyone know whether the feed pipes are the same on the different triple carb equipped cars?
For XK150's there were three different feed pipes used. An early one (C12812), a late one for when an inline fuel filter was fitted and the triple carb "S" pipe (C15283).

Does anyone know whether the C15283 feed pipe for the triple carbs on an XK150S will be the same as the one on the other 4.2 triple carb heads?

Cheers
