This is the thread I look forward to most when I check subs
The first one is always harder than the ones that follow, but things went exactly as expected for the light tube mod, but it would have been nicer and easier if the res was about 5mm larger in diameter when it came to adding the jet tube.
The Bitspower res's, water tanks as they call them, lend themselves to these mods because they have 3 connections (triangularly layed out) on one end, and a single center connection at the other.
All the connections are tapped all the way thru the caps, so you can screw fittings on from inside and outside.
To do the light mod, you need 4 fittings:
An appropriate length of acrylic tube, 1/2" OD by 3/8" or 8mm ID.
1) 6-32 stainless steel screw . . . length isn't critical, but an allen head about 2" long works fine as you need to cut all but 1/4" to 5/16" of the threads off, and all but 1/4" to 5/16" of the unthreaded part off.
And finally, a ccfl lamp of the appropriate length.
Use the G1/4 male threaded multi link fitting on the inside of the single hole cap, and the female threaded multi link fitting on the other end of the tube, with one of the LED caps securing the female G1/4 end.
Cut your tubing to just barely fit between the res's endcaps when they are screwed on, and with both fittings securely on the tubing. about 1/16" gap is fine
Once you have your tube assembly fabricated, you need to drill and tap the 3 connection end cap, right in the center, on the INSIDE
Drill about 3/4 of the way thru, NOT all the way thru
. . . . tap the hole, and cut your 6-32 screw as described, and screw it into the end cap.
Use the pic in post 295 to get a detailed look.
That's your support for the free end of the light tube so that it can't be moved about by turbulence, and cause it to leak.
It's a good idea to assemble everything and leak test now, before you put a lamp in the tube.
I got my ccfl lamps by taking some of these apart: Pick a size that's appropriate for your res.
Once you get it safely apart, you'll need to either remove the connector, or have bought pins, in which case you could cut the connector off and not have to be so careful about removing the pins. CCFL pins are wicked azz hard to get out without destroying them. plan ahead
Now take the second led cap and drill the led hole the rest of the way thru.
Feed the ccfl lamp wires thru the cap and reinstall the connector.
If your newly installed light tube has passed the leak test, you can put in the lamp and cap, and power it up.
Refer to K.3nny 's posts to find his little tutorial on using acrylic tubing.
It will be easier to slightly reduce the tubing OD on each end as he suggests, to fit the Bitspower multi link fittings without modifying them.
There ya go, easy as pie . .
