The original works well enough so no real need to change it, unless its for a new original one.
Where can i find the new original one?? Do you think if i would order aftermarket one with gauge that it will do the same job?? Or i will need to get specific one >??
Thanks!
Mike (phase 1 16v turbo) from here can source you one, he's a parts supplier.
A standard one will do the job fine, if you found you needed more fuel pressure you can always tap the vacum reference pipe off the turbo compressor housing rather then the carb top this will give you few extra psi over boost pressure while on boost.
