Default meth issues discovered while tuning BEF - 07-12-2019, 05:41 AM

Hey gang, having a slow/inadequate meth flow while trying to tune a Trebila BEF.

It's flowing but according to Dave there is an issue somewhere. My current meth setup utilizes the windshield washer tank as the reservoir (I know.....I know....), is tee'd off the washer nozzle lines, runs over to the Aqua Mist pump, through the other thing(name is slipping my mind) and then goes to a tee that leads to the dual CM7 nozzles in a Stett Charge pipe.

I keep getting air in the line between the nozzles and solenoid, but it appears that the line from the reservoir is primed. I replaced the windshield washer pump approx 2yrs ago as well as the nozzles.

Am I missing something? Can't think of anything else other than something clogging.

Got any logs so we can check it out? Air between nozzle and solenoid is okay. Just make sure it's a short distance between the two.

Dave said my run is way too long, which makes sense, I’m gonna shorten it.

Here is my last decent log....

I've done nothing without Dave's input, I'm fairly ignorant to tuning. He stated there was an issue and to make the changes I have stated.

I'm going to shorten up the feed line to the nozzles. I guess maybe I need to look at the tank and the main lines?

So I went out and did some runs today, and in doing them I pulled my squirts while WOT, and boom, no issues, 100% flow.

So, guess I need to go dedicated tank? Even so, do you think I need to replace the pump?

Dave, no joke, no issues if I pull the squirts.

Possible the pump is dying? Or not strong enough to pull through the WW pump?

Any recommendations on what to buy to easily retrofit?

Well, Dave insists the pump trying to pull from washer tank through pump is issue and I’ve been wanting to relocate anyway, so going to install tank and run line. If it isn’t that, then pump.

What tank would you recommend for in trunk behind driver rear tire?

Remove the tee with with the check valve to the wipers as the check valve will introduce air. If you run a tee to separate nozzles the highest placed nozzle will let air in and meth out of the lower placed nozzle thus draining all meth out up to the solenoid. When I had a 2 nozzle setup I used 2 solenoids to fix this. I heard a loop in each line going to the nozzle may help but I never tried it.

What is considered a long run between the solenoid and nozzle?
I'm at approx 24 inches all told, though a bit less. (no issues yet, but new to this)

Mine is probably max 18", but can be as short as 7" or 8".... just waiting on line to get here to get everything done in one shot.

Hi Payam,

Do you mind sharing what the issues may be with a longer run between the filter and nozzle? (Say, 20")

Is it heat causing air (expansion of liquid) that may slowly collect in the high point of the line?

(As in, keep all hot hose as short as possible? )

** EDIT ** my line is 24 inches, from filter (fender, beside break fluid reservoir) to nozzle. Each time I touch the hose, another bubble comes up from the nozzle to the air line and sits in the high point. Currently there is a 4 inch bubble. The air comes in when the nozzle drips, just sitting there. Only fix in my mind is to mount the nozzle on the bottom of a CP so it doesn't drip. Since I cant do this, I believe I'll curve my hose down (maybe mold in heat) so that the maximum drainage (and thus bubble) will be no more than 2 inches.

Very open to other experiences and opinions.
