QuoteAlso, no extension hose on my pickup.  Do I need this?

Measure it.  Should come to about 3/8 to 1/2 inch from bottom of the tank to the high point of the notch at the bottom of the pick up.

If any other thoughts, I'll take them


Hence, what I have said on here way, way too many times.

Do NOT play Whack-a-Mole and start replacing parts Willy-nilly.

It can get frustrating, waste valuable maintenance/repair/sailing time, unnecessarily consume boat bucks, diverts good beer (or other alcohol) money, and can lead to sleepless nights asking the question, "Was that the root cause, or a coincidence" (it is a boat after all.)

troubleshoot - Troubleshoot - TROUBLESHOOT. 
Then, start replacing parts willy-nilly.

Isolate and test (or bypass) a suspected bad part if possible.

QuoteI think M35 is self bleeding but I bled anyway.


I have opined many times that anyone with a Universal that doesn't have the knurled bleed knob (such as an M-25) should install it.  And anyone who has the knob as OEM (such as an XP) replumb the fuel flow so the knob does not return bled fuel to the tank (as i did.)

This makes troubleshooting more straightforward and allows viewing the fuel flow/condensation while bleeding. The OEM setup prevents that, which for Kubota to have done that was, using a technical term, plain stupid.

If one wants to retain the option of returning fuel to the tank that can also be accomplished.

The good news is that I am back up and running.  Thank you all for your input.  The bad news is that I am not EXACTLY sure why, lol.

I started at the tank with the pickup, then to the Racor (changed to new), the pump (new), then to the secondary filter.  When I pulled the hose and ran the pump, it dumped some debris in the container that I was using.  I don't know how this got through the racor but there it was.  I changed the secondary filter, reconnected everything, ran the pump for a bit to bleed and after a few tries, she started right up.  Ran for 20 minutes at idle, at 2000, and in and out of gear.  Sounded better than ever and started up faster than ever.  Upon changing the secondary filter, I noticed that that bracket was completely broken (discussed at some length on this forum many times).  In reading past forum entries, these brackets from Westebeke went from being free, to $22.00 to now $65 + shipping.  That is some inflation.

Thanks again!
