Line vs. load- I usually use the center two screws as load and the outer two as line in. You are getting power to the pump or it wouldn't be working. Try backing the cut out control nut out to reduce pressure "the one with the short spring located off center". If all else fails remove the switch and unscrew the backing plate, remove the diaphragm. You can test the switch manually by pressing on the center of the mechanism with your thumbs. Also while you have it apart look through the inlet pipe. The actual water inlet hole is quite small and can become clogged. Reassembly doesn't require any kind of sealant.

1/2" bolts fit through the holes with enough clearance, holes are not perfect.Center to center is 1 7/16 to 1 1/2"

It has four bolt holes one on each end. I have two screwed in wood deck and another on on concrete. Holds wells with proper mounting.

That's the bolt pattern. (It has 4 bolts.) The bolts are centered on a 4" diameter.

When I bought this pump, the gasket was included. But it should be a standard part at a local hardware or plumbing store.

Pump includes two check-valves, one on on the backup pump and one on the primary pump. They are actually located at the bottom, where the white PVC pipe connects to the pumps (just under the rubber pipes). You can see the diaphragms if you look down the pipes before you have installed it. Note that the instructions included are incorrect in several ways because Wayne sends the instructions for both devices, not the components as a whole (which includes the check valves). In my case, I left my existing check-valve as an extra pre-caution and haven't had any issues. As an aside, the instructions also indicate that you need a weep hole. However, Wayne's website indicates that one is not necessary because "Wayne Sump Pumps are designed with a top suction inlet. This design naturaly [sic] prevents airlocking [sic] which eliminates the need for drilling a weep hole."

The flange is interchangeable it is the bolt patter that matter. Bolt pattern is the same on the model number. The difference is the pump mount

The bolt holes measure 4" on center, across the center hub. I put these on my pop up and they worked fine.

The vehicle is no longer in our shop in which we installed the pump. If my memory serves me, it was 5/16" inlet and outlet. Please don't hold me to that. It may have been 3/8".

Hi, if your vehicle still has the original pump you need to change the thermostat,the thermostat is a new design and also the water pump. the thermostat is one complete unit including housing. as for new bolts my old bolts work fine.

I believe either 1/2" or 3/4". You should be able to find specifics on basepump.com

These are for perimeter bolt valve covers. I saw some for center bolt but don't have the part number handy. Also these will need to spaced up and away from valve cover or customized some in order to clear some headers which I had to do when I installed them. They have center bolt ones but they look different than these.

On the pump I had to take the old and new pump apart at the impeller housing to make it work. I had to use the old impeller housing on the new pump. I tried swapping the mounting bracket on the pump but bolt holes did not line up. Vern

Not sure but I have only seen the pumps. You should go to manufacturer's site to see if you can get more details. Sorry!

There is a key slot in the pump and it must align with the key on the main engine. Very, very easy to assemble.

I think its a standard 3 hole size. I had a triangle flange too, this bolted right up.
