I bought mine from Globalriders.com. I have loved it. It works great, no muss, no fuss. My only complaint is a very minor one. I got the smaller version, and have to pump it about 3 times to suck the 4.5 qt out of the Escort. Just to test, I opened the drainplug when I was done, and didn't get a drop. Klutz that I am I only made a mess when I took off the filter. Oh well.
BTW, I have no affliation with GR.com, but they did give me the same pump for less than the then advertised Griot's price. Just a suggestion.
