I have not found anything on Amazon, other than used OEM and I was looking for a known alternative that would fit with same diameter in and out and electrical connector that would fit the limited space allowed. My old one stopped working, I figured brushes could be replaced and took to an alternator and starter rebuilder who had same size brushes in stock, but it was to far gone with armature fried in addition to brushes so I have ordered a used OEM off eBay. I figure there has got to be a new alternative but just haven't been able to find myself, so if anyone has that information it could be of value to others, including myself who would benefit from a less expensive option.

Thank You exjay8 :-)

And just to confirm, your links have known same diameter hose fittings both in and out, same electrical plug fitting and will fit space allowed ?

You can easily splice your electrical connector to the replacement pump as long as the correct polarity is observed.

I never really care about the electrical plug or the pump diameter as long as the hose fittings are the correct diameter.

You can cut the bracket off and use hose clamps to remount the replacement (or fabricate a bracket?) but the hoses do need to fit!!

As far as I know I think they do, that's why I saved them in my Wish List...you can look up the specs on the page.
As Motorcarman has stated...it's the pipe dia. that counts....the rest is an easy mod ;o)

I bought alternative bosch made pump to replace pump that may soon ish broke. (not mutch brushes left). Bosch has tiny bit smaller diameter hose fittings but will suffice ok. The thing what may give problem is that the original pump is magnetic type and replacement is not. Will this cause issues ? I don't know this mutch of fluid dynamics.
What causes my concern is the temperature valve. Valve regulates water flow by going full shut and full open as we know. With oem pump there is no problem as pump is magnetic type. There is no any kickback to the pump. But with replacement one there will be.Time will tell what happends then.

I have an extra one in garage as well is the upgraded Bosch supercharger water pump. They are the magnetic type and can replace top/bottom separately in worst case scenario

This means you combine old and new pump parts because of different outlet diameters? Could you tell us the replacement part numbers?
