I need to test the fuel pressure for my 91 Accord LX 5-spd, but I need an adapter for my fuel pressure gauge. I have 1/8" NPT male coming from the gauge, and I need to know where to plumb into the fuel rail/lines. Is there a commonly available part to adapt the rail to a ****** fitting or 1/8" NPT?

 

This requires a special banjo bolt adapter that I have not been able to find either. Haynes has a description in Accord manuals of how to make an adapter, but the procedure would require either a drill press or some very good nerves to drill a small hole longitudinally through a 1" bolt length. I've tried that before and it's not easy. The bolt is 12mm diameter x 1.25mm thread pitch, if you're game.

Honda apparently specializes in creating pressure ports that require unavailable adapters. Their transmissions have similar unavailable pressure adapter fittings.

Post if you find a suitable fitting.

good luck
