I was under the hood yesterday, still at the house... Getting ready to leave, one of these days...

I was just glancing at all of this yesterday, not much thought going on as I was messing around elsewhere, but had the phone and took a few photos...

Anyway, I took a photo of the side of the IFSM, there is a compucheck port, and wondering if this is a spot that a fuel pressure sending unit can be installed? Or would it be the bottom port, with the nipple on it at the nose of the unit, below the where the main fuel line exits the IFSM. Or, where Pd6 has his down by the fuel filter? I don't know if I will do this, just thinking outside of the box, and the gauge is available...

I was told (and that doesn’t mean the advice was right) that you’ll get a low pressure fuel code when your pump is on its way out.
I’ve got a fuel pressure test kit on order, it plugs onto that compucheck fitting. I figure to check it every service, just to keep an eye on it.
It comes with a fuel restriction gauge, too

Can you post a link to that fuel pressure kit?
