how about the fuel filters and housing being plugged up??
housing drained cleaned and blown out . fuel filters new .
the problem now seems to be no fuel to bleed system period.
Hence transfer pump?

or the line going to the pump. i seen them 7/8 full of crap at the lowest spot, not necessarily at the pump.
fuel line while disconnected from transfer pump/ check housing pours out like a hose.
there was considerable sediment in the intake orifice of housing between
fuel line and check assembly.
discovered clean out gallery above hour meter, flushed out through
filter housing.
Does fuel enter filter housing through pipe against back of housing?
How do I remove transfer pump for an inspection?
Did you fill the filter tower with fuel after changing the filters or are you depending on the transfer pump to fill the tower? Yes fuel enters the tower through a tube that discharges just below the filter support flange.
after the initial hic up. after fueling up while trying to restart I noticed absolutly no fuel pressure.
then open housing to inspect filters and noticed that it is low so added a quart of clean
fuel so it spilled over when the filters went in. then restarted pony, lever in start, throttle
closed, all bleeders open after a few minute's small amounts of fuel out of bleeder on face of housing, close it, but
no fuel out of top of housing?

Yes the fuel enters through a port at the back of the transfer pump sealed by an o-ring,
my 7u has a similar problem, engine would miss at low idle and really sluggish top end due to the low fuel pressure, tried all the obvious things first than pulled the transfer pump off and striped it down and the gears had chewd out the body of the pump, now waiting on parts from cat, nearly everything I needed was available, my pump was also extremely hard to remove, took a fair force to the point that I thought i was going to break something.
your sure you have removed the correct four bolts? mine had two bolts that went threw the whole pump and two studs with nuts that only went threw the most inner part of the pump,
good luck!
If you must remove the pump there are two nuts on the short studs next to the engine.
One nut on a short stud on outside rear of pump
One cap screw on the outside front position on the pump.
Pump needs to come straight out.
You never indicated what the fuel pressure was so you may be wasting the effort removing the pump.
