@KW - I didn't see the part number from the Kubota manual - perhaps it varies by application?  Part ordered. 

Kumar Bros doesn't carry IP, but bookmarked as a source for parts. 

It's the same model pump from the same model engine - I would assume the same shims, but I'll check.  Thanks.

PM me about the cushion covers.

The bleeder valve seems specific to the marine version - $30 valve and $15 shipping.  Sign.  No readily available replacement injector pumps out there - everything is orderable but out of stock.  I pulled the trigger on a remanufactured unit and will rebuild the one I remove as a spare.  Pricey bleeder valve ordered, as well. 

Reading in on the Kubota cross-reference, new at $699 vs $2200 for the marine version. Rebuild kit is about $30.

I opened the high pressure lines and I'm getting no fuel to 2 of them.  I suspect a failure in the injection pump.  I could tell that the mechanic at the yard took a look - left the batteries to ALL and the keys in the ignition! Waiting for confirmation.  1 available on eBay.

New update. No change.

I ended up biting the bullet and went with the West Marine system. 

Update:
The air bleed screw broke off immediately when I tried to open it.  I moved to the injectors, per the above recommendations and only had fuel flowing from from the first injector.  I verified flue flow to the overflow.  I next swapped the fuel filter, left it loose, and ran the pump until fuel spilled out.  I moved back to the injectors, but with the same result.  The fuel coming through is clean.  I plan on repeating the bleeding at the filter again and going back through the previous steps.  Suggestions welcome.

FWIW, it wouldn't start before I touched the fuel system.

I bled at the filter. Will try the injector pump on Friday when I get back to the boat

I went with the pigtail option.  I verified that the fuel pump was only turning on with the ignition.  However, I'm not able to get the boat to start.  I removed and cleaned the fuel separator.  I checked that fuel is flowing (and bled the separator).  If I spray starter fluid into the air intake, the boat begins to start, but doesn't run.  The engine cranks well.   

Just to be clear, the fuel pump wiring is not part of the replacement harness.  It has ring connectors and the positive and negative wires, fwiw. 

For the replacement, I used ring connectors and replaced the wiring from the engine to the new gauges also using ring connectors.  All of the gauges are working correctly.   

The boat had the original wiring harness and the PO hadn't done the critical upgrade.  I bought the replacement from CatalinaDirect.  The previous was the standard RV connector, but the fuel pump isn't part of that harness, in either case.  In the original, the fuel pump connects to the ammeter, which I replaced with a voltmeter.

I replaced the gauges and wiring harness to the engine.  I'm not sure where the fuel pump should be connected.  Help!
