Looks like I need to step in here, First this pump in not a copy of anyones, I never saw the the EEP pump. Look at all of the other companys selling electric water pump, I guess that they are all copied from the manufacture that made the first one. Did company "A" build the first one, and company "B,C,D" copy them ? Yes the design may look the similar,but there are only so many ways to put a electric motor on to a specific piece of material in a specfic place.
I know who makes the pump for EEP, and they make great products. As far as theprice go's, when I started this project I contacted 3 major companys that make electric water pumps about the idea. 1 company said that they could'nt help me because they have a similar item.(EEP-?) The other 2 gave me quotes that were very close incost. I picked a mfg and had them made.
(I don't feel comfortable with the next part)
I was contacted by the person that made the EEP pump. He asked for a price, I pm'ed him back with a price, then I got more pm's from him. He asked why I was selling this product so cheap ? I stated that I was selling it for a fair market value, He than stated that fair market value is $500.00, since there are no other ones out there. Yes I could sell it for $500.00, but I don't feel that that would be fair for the customer (I don'y need to put my kid though collage on 1 pump)
As far as a beter pump, I don't know. I will say the motor is 1 or 2 steps above the motor on the other pump. Motors come from the same source. Also look at the motors they are different,along with the mounting plate, and the impeller.
One more thing, look at the other stuff avalible for our trucks, the price for stuff is all over the place. Arp studs for a 12v-from $390 to $560, why the big difference ?
Sorry for the rambling
