Back to problems. Ive got intermittent meth flow. Most of the time none at all, sometimes the lights flash for 1 or 2 seconds and then back off, heck sometimes they stay on for a few seconds. I purged the lines and all, flow is perfect, no clogs, no leaks, etc. The problem must be from the exit of the pump to the charge pipe. My lines are fine etc, could this be the flow sensor failing? Have others seen this with the PWM kit hardware? Im open to trying whatever. This has been occurring recently, where are previously everything ran perfectly. Ive changed or touched nothing. Thanks, kinda confused.

Post a log of meth flow.

Make sure your back flow valve is not letting air into the line. You can plug the wiper line to see if that fixes the issue. Also check clamps on filter and your T connector. I had the same issue and ended up replacing the zips for plastic line clamps.

to connector and all filters, lines, are perfect, same as day i installed. logs arent going to show much for this issue IMO aside from meth flowing or not. idk what else to test aside from these things. as much as it seems like the meth solenoid is bad, its probably not that.

The logs will actually help, it can be a difference of air being induced into the system mid-pull or a sign that your flow has simply reduced over-time. Methanol systems do require a good amount of attention.

Wedge had a good point about the back flow valve, its a common failure point.

so, blow against flow direction of check valve then?

[plague]

also when i purge my line, it flows perfectly, so the problem would have to be from the meth solenoid to the charge pipe but everything looks fine..?

My WW pump went bad (started leaking) shortly after I started getting intermittent flow but mine was going on/off like every 0.5 seconds during pulls. I did not see anything unusual while purging the system and it would work sometimes and not others.
A leak under the turn signal side marker on the passenger's side is what you see when that thing leaks.

This.

Mine came loose after like 7-8 months so i tightened it and that fixed my intermittant meth flow.

yyyup. just got home. realized. huge leak coming from that area. about 10 inches behind the passenger side fender. washer tank is definitely leaking badly. bingo. this caused your car to do that same thing? flow was intermittent and this was your culprit? my windshield sprayers spray perfectly fine, so this would cause intermittent flow of methanol how exactly? fluid is still going to be pulled from the tank just as easily isn't it?

I think the difference is that when using the wipers the pump actually works and pushes fluid. And you can't notice any air in the line simply because the nozzles disperse the fluid and I think the pump capacity is way over that of the nozzles.
When running meth you have a much powerful pump sucking fluid trough the wiper pump and I think that allows for air to get sucked in through the worn seals.

Happened to me as well. The high meth concentration (70/30) corroded in two areas where there was rubber grommets both at the pump and the pour tube. I'm only running 50/50 now.

The WW tank leak and intermittant meth flow have nothing to do with each other.

They did for me, I replaced the leaking ww pump and my meth flow went back to normal.

replaced leaking pump. didnt fix flow. its not even intermittent anymore, but totally absent. none at all.

This happened to me when I had air in my lines. When I would floor it, no meth. But then when I activated my windshield wipers spray, meth would flow during the WOT run.

It was fixed by simply tightening the white screws in the flow line.

Everything is perfect again. Thats exactly what i was doing today. Took it onto the highway and under boost, pushed the windshield sprayers, and meth was suddenly spraying and indicator lights were holding perfectly. The moment i stopped spraying windshield, the meth would stop. After a few pulls of this, the car was spraying meth perfectly, through all gears, without spraying the windshield anymore. Just took it out to dinner tonight and it worked wonderfully all night. After replacing that leaky pump there was probably a massive amount of air in all of my lines, from sucking in air through the leaky seals which were a flaw in the 'air tight' system. Who knows maybe even some gunk or something inside them a little bit from hardly running it over the winter. I have to say i think its running better than ever. My spray was never this constant and solid. Noticed i would have times when i wouldn't spray for a few seconds or sometimes it would be choppy. Thanks for the help to the two of you above.

Awesome glad to hear! Did you check to see if the white screws in the flow line were tight? They come loose after a few months and you need to tighten them. That's what was causing my intermittant flow and using the WW spray only helped temporarily.

yup. my white filter screws were tight as could be.
