I’ve only bought oem coils. Don’t know which version the knock offs copied. See old and new part # photo. I hope 853-01will be in the PN train. I went through eight coils in 80,000 miles. The 7th and 8th are the new part number and now have 140,000 miles on them. It’s worth buying oem.
Never have I seen the six screws corroded. The female holes are tapped straight into the aluminum tank. I’d soak the screws in penetrating oil for a few hours. Then, while tapping a breaker bar and Allen socket set up with a 16oz hammer, turn them 2° to 3° tight to shock and fracture corrosion. To be on the safe side, soak them again with penetrating oil.
I’d bite the bullet and buy oem hoses for inside the tank. Again, you don’t want to make multiple trips into the tank.
If your S is a BCR, they had no QD’s. If your bike had plastic QD’s they would have broken by now and a previous owner might have replaced them with straight hoses. If so, pinching works just fine but make sure not to reverse supply and return hoses. There are faint arrows showing direction of flow on the outside of the fuel plate near the hard tubes.
