Fuel pipe question ??

GTX fuel pipes GTTurbo engine
As always thanks for the previous replies, trying to get this running at weekend.
Have mounted my fuel pressure reg, the 2 fuel pipes supply and tank return come up near the brake servo, 1 is smaller in diameter and doesn`t fit onto the FPR. Would the smaller one be the return pipe ??

anyone

On the GTT both pipes are the same diameter (5/16" or 8mm). On any fluid pressure system, the smaller pipe tends to be the Pressure and the larger pipe the Return.

OK thanks for that, kind of makes sense as the smaller outlet on the FPR is the supply one to the carb.
I also presume i need to fit the GTTurbo fuel pump. Also the GTX has only one fuel tank no auxillary one, does this matter ??.

The Auxiliary Tank just feeds into the Main Tank and all pressure and return lines start and finish in the Main Tank. Some members with track cars remove the Aux Tank and fit the filler neck from the Campus model.
