I'm about to order some last parts I need. My fuel system should consist of a Holley blue fuel pump with a Holley regulator, though I still haven't figured out if it's the high pressure version or not despite my attempts to ask for any markings to find this out.
But I want to run a 1/8" NPT fuel pressure gauge in a tee fitting on my regulator. I can either get a VDO or a Marshal, though I've never heard of Marshal. The Marshall is also available liquid filled. Prices don't vary that much. Does anyone have any experience with either?
Please let me know
