PVC Help

I did some quick Googling and this seems to be a common problem. A lot of people seem to have had trouble with that 3/8" side of it. Might need to be an internet purchase.

A number of people ended up going to USPlastic.com and getting two pieces:

The first is a "reducer" to go form 3/8" up to 1/2" and then a 1/2" threaded to 1/2" slip

Of note though, it really isn't 3/8" either. It is metric and 3/8" will work with some teflon tape.

Here are a couple of threads about it and the 1250 and 1260 pumps:

I'd do more digging, but I am already a couple of minutes late from driving part way to Des Moines...
