And the siphon assembly itself. The black line from the bottom is the pressurized fuel supply from the pump. It goes through the siphon and then out the other black line that attaches to the bottom of the main module cup. The siphon itself fits into the top of the siphon cup with an O-ring seal. As fuel flows through the siphon it pulls a vacuum on the siphon cup tp pull fuel from the RH side of the fuel tank.

Here the siphon assembly has been removed from the siphon container. You can see the feed nipple at the bottom which the internal hose from the RH side of the fuel tank attaches to for pulling the fuel over into the pump module in the LH side. It appears to have an O-ring fit at the bottom, but I didn't try to remove it.

Looking down into the pump module cup. You can see the cup inlet flapper valve (blue/orange device). The S2 flapper and inlet hole are larger than the S1 pump module. As the pump pulls fuel out of the cup the higher fuel level outside the pump module will push open the flapper valve and flow into to equalize it. You can also see the siphon device that has it's only siphon container housed within another smaller cup in the main fuel cup.

Here you can see the pressurized fuel line to the siphon assembly. The black line going down the side f the module cut is the fuel being discharged from the siphon assembly down and into the bottom of the cup. I have the discharge end disconnected from the bottom cup inlet nipple for it.

So again, the is the fuel discharge appendage on the fine filter with the main fuel discharge hose out of the top and the pressure relief devise out the bottom. The small black line out the side is pressurized fuel that goes to the siphon device to pull fuel from the RH side of the saddle-style fuel tank over into the LH side.

The removed sock rough filter and the relief valve. The relief valve has two O-ring seals. You can also see how the sock filter attachment also keeps the relief valve locked in place with attachment clips.

You can see the Denso pmup ID here. This is a type "65C" pump. Any replacement 65C pump should fit the module without modification.

Here the sock filter is removed and the bottom of the pump and the relief valve can be grabbed onto and pulled from the fine filter canister. The fine filter canister is also replaceable from Mazda.

At the bottom of the fuel filter discharge appendage is the metal relief valve. It discharges directly back into the fuel pump bowl. It's also removable/replaceable and secured in place by the sock filter attachment device. Once the sock filter assy. is removed, you can then remove the pump and the relief valve.

This is the basic pump and filter assemble. The The rough sock filter is at the bottom, the large white canister is the fine filter, and the pump is housed inside of it. So the pump draws in fuel from the sock filter, pressurizes it, discharges the fuel into the fine filter canister, and then the pressurized, filtered fuel is discharged into the white appendage on the bottom tight and out the black corrugated hose on the top to the engine.

From Pete C: The header pictured was a custom piece we were building for a customer that was racing the grand am series. Labor was around 500. They were built out of 321 so the material cost was pretty high.
