need guage/fitting to check fuel pressure...

[90 Gen2]

Hey folks, not sure if I posted before about this, can't find it on a search...
Most parts store fuel pressure diagnostic guages do not come with nor offer the fitting recommended by the factory service manual ('90 3S-FE) (8mm banjo) to check the fuel pressure on our car. Someone must know where this can be found, or an easy workaround.
The factory manual suggests installing the fitting between the bolt head and the cold start valve with an additional crush washer I think. Seems very easy if I could find the fitting and appropriately ranged pressure guage!

Thanks for any help!

might have answered my own question, looks like according to Actron's website, their adapter part # 0180-000-1297 does the job for their fuel pressure gauge. I'll try to have that ordered locally, unless someone else has a better solution...
