Water Pump Advice
My '50 F-1 has a leaky water pump (left) and I was wondering whether I should do both or leave the right one alone since it seems to be OK. And should I try to rebuild it or get one already done? I have no experience with this. Thanks in advance.

No reason to replace something that's still OK, but then again when you flush your system as part of the replacement procedure, you could well trigger leaks in the other. Roll the dice, take your chances!
Pump replacement is a golden opportunity to clean out that side of the block's cooling passages.
I bought my replacements from NAPA (rebuilts) and have been completely satisfied with them.

Change both, and preferably with new rather then rebuilt, it’s been a while but this is not a ten minute job and not something that you want to be doing again.
Very short story, kina related, many moons ago as a broke high school student I climbed down in to a land fill that had old cars in it to get a flatty water pump, steep bank, long ways down, hot, some guy dumped a load of tires over the edge, so I had to bail to inside one of the cars for cover, darned near killed me. Finally got the pump off, tough climb up the hill………………………………………………it leaked worse then the one on my car…………bought a rebuilt one!

Note that to get the radiator hose off the pump, you loosen the radiator bolts on top and remove the rest, swing the bottom of the radiator away from the engine (have to remove both hoses off both pumps). Yeah, there's that water all over...
Also note that there is a bolt accessed thru the lower hose opening, if it's been in there a long time it may be a #$%^& to get out. Some folks go back with a SS bolt, for sure use a sealing compound on the threads.

Water pump rebuild?
Has anyone attempted to rebuild the pumps thier selves? I am do a complete engine rebuild. Why I am waiting on the block at the machine shop I thought I would attempt to take apart a water pump. I see rebuild kits are readily available. The short of it is I will be buying new pumps. I bent the pulley tring to get if off. There must be some tricks here.
Thanks, Scott.

8BA pumps are not that tough to rebuild, but I doubt you could save $20 each, and if you bust something...
Upgraded pumps, if you really think you need them, are available from several places. I'd stay away from Speedway's IMO.

Water pump?
I appreciate your advice. I was actually looking at the speedway pumps. What issues have you had or heard about on these?

I've not used them myself, but I've heard others say both good and bad. Check this thread on the Flathead Forum, but keep in mind some of the discussion is about 59-series engines:
Ford Flathead V8 .. 1932 thru 1953 • View topic - Speedway water pumps
Saw some traffic on the HAMB about them too, but in general they hate Speedy Bill.
