Default Fuel rail schrader valve

Hi all, i bought a cheap fuel pressure gauge to check my supply. None of the connectors fit the valve. Has anyone else had this problem and found an alternative fitting ? Ones I've seen are an arm and a leg! Thanks for any assistance in advance.

I used a flex tube from can old Fix a flat can, a copper barb fitting and cheap liquid filled fuel pressure gauge from Summit or Speedway Mtrs. WORKS GREAT

The problem is a lot of these Chinese fuel pressure gauges come with a whole range of connectors and look very impressive in the photos, until you open the box and find that none of the connectors actually fits the Schrader on the car, which as you say is just a standard size. It's a bit of a mystery to me.

This is the one I've got: https://www.machinemart.co.uk/p/clar...sting-kit-tes/

Not terribly expensive, but works great.
