So unless some of the parts in those drawings are foam or similar type material it allows for unfiltered air to be sucked in when opened, which is probably better than water.

The outer layer is a foam filter. Not the best filter, but it also isn't using that filter all the time, just when the bypass valve comes into use.

So I would think you could install a T and simply cap the end of it

Exactly. That was my thought from the start, but then the guy at AEM said they wouldn't recommend that. But after thinking about it more overnight I think that's what I'm going to do as a stop-gap measure......especially since I was able to see the construction of the valve better in the patent drawings. But eventually I want to make my own poppet valve design with a better filtered inlet.

After learning from you guys, I decided to try plastic welding the reservoir. While trying to find some polyethylene tube/pipe, I realized that the jug you buy washer solvent in is made of polyethylene, so I cut the straight middle section out of the jug and then made a cut down the length of it. After that I overlapped it until it was the correct diameter. Then I welded that seam shut. I forgot to take a picture of this part, so hopefully that description makes sense. Then I inserted it in the holes I made previously and started welding the tube I made to the reservoir. I went all around the top and bottom of it. It’s a long, tedious process.....or at least it was for me since it was my first time. You’ll see in the pics that I started using the black filler rod that was supplied in the kit, however after a while I realized I could use pieces of the jug as my filler material so I wouldn’t have black smudges. Well, I got it all welded and.....it still leaks.......apparently I’m not very good at plastic welding. I’ll keep working at it tomorrow, but right now my eyes need a rest.

Ha great attempt for sure , the welders i have used blew hot air so a bit different than a hot tip . I dont know of any plastic fab shops up there the.one i worked at in high school is closed( long time ago) lol

I can see hot air being nice for the welding. I was thinking about preheating spots with my hear gun and then doing the final weld with the iron. I’m going to need to grow a 3rd arm.

I have both and I like the iron alot better. The problem for me with the hot air was it was too easy to heat up more than I wanted and then it would sag. I would have thought that the washer fluid container would be alot thinner which would make it more difficult

Yeah it’s a bit thinner and I’m sure it isn’t helping me learn how to do it. It’s like learning how to weld on sheet metal. I’m just trying to use the materials readily available to me. If I can’t get this to work, then I’ll go buy a sheet of thicker stuff and try to roll it into a tube.

Reinforce the plastic weld with metal screening just melt it into the area being welded...........

Is the screen to reinforce the joint to make it last longer or will it help with making the joint more sound in the first place?

I imagine that making a leak proof plastic weld bead is a lot like making a leak proof weld bead in steel or aluminum. Damn difficult if you aren't doing it all day long every day.

One thing i should have mentioned first.. absolutely no oils or it will not weld well

Yeah, I was going to suggest wiping everything down with MEK and letting it dry before welding.

Ok, thanks for the tips. I cleaned the stuff, but not super thoroughly.

If you don't have any MEK (MethylEthylKetone), acetone will work fine, just don't use nail polish remover acetone, as it contains fragrances and skin moisturizers along with the acetone.
