I bought the 'uprated' pump by Bastuck from BPNW (the AHSpares
offering appears to be an unbranded version, or maybe a copy). The
impeller appears to be somewhat more effective design, and the gap
between the impeller and the pump body is, I think, smaller than OEM
so would likely flow better. The threads on it won't fit the OEM
valve--I think everything's metric on it--and it comes with a barbed
nipple. As previously reported, the hole on the top of the
pump--anyone know what that's for?--comes with a plug that doesn't
plug; I tried everything to get it to seal, and ruined a pump in my
attempts. I finally found a way, and may use it to seal an O/D drain
plug if it continues to leak. It works fine, but I haven't had the
car out on a hot day. I don't think coolant flow is the cause of
overheating, esp. at idle; it's mainly due to lack of airflow
through the engine bay, lack of a shroud, etc.<br>
<br>
I was so desperate I even tried a County pump, bought from Tom
Monaco but sourced by Moss. The bearing felt rough and and I didn't
install it; I returned it, and Tom had to jump through hoops to get
a refund but he came through. Tom knows a rebuilder in Oregon who
rebuilt an OEM pump for me, but it's currently riding in the boot. I
don't have the invoice, but Tom would tell you if you gave him a
call.<br>

<div>AH Spares professes that they have the best pump. Many other
aftermarket makers, including County, make junk. Using the
original parts can work if you have someone who understands
pumps.The proper spring pressure is critical to prevent leaks
and the seal being made out of delrin resists wear from
vibration. This machinist worked for an agricultural supply
