@motorman7 I think I paid about $150 for mine on Amazon

I would "vacuum " that out with an electric fuel pump. Then analyze what you take out for a diagnosis...

I would try an induction heater on the manifold and flare nut wrenches. I would probably heat it, soak it, heat it, soak it, then heat it and try to unthread them. I have gotten things apart with my induction heater I thought would never come apart!!

Maybe the crap in the tank is too large to pass through the filter screen in the tank. It just blocks it up instead

I would use a small electric fuel pump and some hose sections and maybe a small tube section and pump it out into another container. Diesels can get algae in the tank but I've never heard of that in a gasoline car...

I like foil tape. I use it a lot at work. It sticks really well and is nice and malleable

Modern cars tend to run a little lean at cruise. You just have to be careful. Too lean will burn valves and damage pistons

Foil tape doesn't hold paint well. It might if it doesn't move much

I do not know if the afr number to the fuel supply is directly relatable I dont believe a super lean afr is 0 fuel and pig rich is an Afr of 1. Its a ratio so an afr of 1, is 1 part air to 1 part fuel. How is each part measured? What is the unit? Stoic is 14.7:1 So if you're at 16:1 your fuel needs to go up by 8.8% I believe, maybe, possibly...

Not that I know of. It would give you an idea of where the stations need to change and whether a little or a lot but I dont think you can calculate exact station size required from wide band afr numbers. You would also need a visual reference for piston height (station being metered) at a given AFR. There are quite a few SU needles available with station sizes but like tuning webers there is some educated guesswork

No way to remove that, that I know of. The discoloration is normally caused by delamination of the plastic layer in the middle from one of the pieces of glass. If most of it will be covered I would install it. I wouldn't use a sealant unless the windshield leaks. If it does, you should be able to pry up the edge and squirt it under at the leak locations

I believe one switch has two wires and the only one

@nix240z Steve, Did you ever reproduce these?

I think its easier to put the glass in first
