Measure fuel pressure

[NeverSea]

How to connect? I already have a gauge (as in the picture).
thanks

that's an impressive kit
but I don't believe you need any of the numerous additional parts,
just the gauge with its attached hose.

Remove the black plastic 'dust cap' from the engine fitting you've pictured
and the end of the gauge's hose should screw right on there.

I believe that gauge hose has a quick connect fitting on the end , so you would need to find the proper fitting to screw onto the motor fitting so you can snap the quick connect hose/gauge on to it.
I have no idea what threads are in use on that.

[NeverSea]

I tried to choose a suitable fitting / hose but it did not fit the motor connector. I need more What is the size and size of the coupling? My gauge joint 1/4 "

[99yam40]

Oh, so the gauge hose is a threaded fitting and not a quick connect.
maybe like an HVAC gauge fitting?
I did not see the threads the 1st time.

so did you try all of those different metric adapter fittings in that kit?
maybe fairdeal knows for sure what the thread size are

Are you running the boat with the intake plenum off or on? Cowling cover on or off?

And nary a mention of the model of the motor.

I just got a new set of pressure gauges. I want to check it

As noted, the gauge should have a fitting at the end so that it can be screwed onto the Schraeder valve. After removing the black plastic cap that covers the valve.

I can't find a tool to attach to the injector rail. Anyone have another idea to measure pressure?
thanks

In the reviews for that tester kit on Amazon, one can find this:





and in the "Q&A" section this:




this is the Amazon listing for seller's "other kit"
that has a standard Schrader valve connector

I modified the spare parts I have (as shown in the picture), I will connect this connector Yes or not. The oil must splash.

[99yam40]

I have no idea if that will work or what the oil splash means

[NeverSea]

I will try it How did I get the results? I will update again, thank you.
