hi guys my mate has a pin whole leak in a solid fuel line
is there an easy fix
its spurting like a mini jetwash.

No.

Where fuel is concerned spend the money and replace the pipe.

A very quick temporary fix might be a patch of fuel safe rubber under a suitible size jubilee clip tightened down where its leaking from.

If its a standard plumbing size I'd see no problem with cutting it and putting a compression socket in there.

You could even cut the section out and join it with some flexible correctly rated Fuel pipe with a fuel pipe clip on either end.

cut it and join with a piece of rubber fuel hose and suitable clips, no worse than the link between the rigid line and fuel rail
