how to test fuel pressure?

i just bought a fuel pressure tester kit.and it looks like it doesn’t fit into the fuel line anywhere(even with the different attachments).I can’t find a schrader valve anywhere(do tegs have one?) how the hell do i test the fuel pressure cuz my teg won’t start.It cranks but won’t start.

by removing the service bolt at the fuel filter you should be able to attach a fuel pressure gauge. it doesnt have a schrader valve though.

but the fitting on the fuel pressure guage i bought looks like it screws onto a schrader valve,but you can’t screw it into the fuel filtr fitting

Most compression testers sold at the auto parts store will include a fitting for the fuel system, but I only do that if I realy have to, Im not sure of the effects of ruel and the scrader valve.
