A couple days ago I got some new Paasche bottles and lids w/tubes.  I noticed that the tube fitting on the 1oz. bottle lid was different than the lid that came with the air brush originally.  Not a problem,except that this tip/how to would not work with this new style? lid w/tube...so I came up with a working solution.    
Newer style lid w/ tube on the Left, the original VL air brush lid w/tube on the Right  
  With the newer style lid (Left) the vinyl tube fits inside the fitting.  With the original VL air brush lid w/tube (Right) the vinyl tube fits over a barbed fitting.    
 Newer style lid w/ vinyl tube removed
  This old CA glue bottle nozzle will become an adapter that goes between the lid fitting and the vinyl micro fuel line.  Be sure and clean any glue remnants from the nozzle...I used a drill bit and blew it out w/compressed air.    
  Remove the threaded portion of the nozzle...avoid cutting into the inner flange of the nozzle, this is what will end up fitting over the lid fitting.  

  Remove the grooved ridges from the base of the nozzle...remove enough so that the nozzle will fit up into the lid and the lid can be screwed to a bottle.  Taper the tip enough so that the vinyl micro fuel line will fit over the tip.    
  Slide the vinyl tube over the nozzle  
  Firmly press the nozzle over the fitting.

First off a salute to my fellow veterans on the forum..... I have started to work on the packer body and its separate components. This is from the Garwood sales brochure for the LP 900 packer.  This is the view looking forward towards the truck cab from inside the packer body.      Here is the same part from the kit.  The lower portion and upright portions are part of the hydraulic tank.  I am going to be displaying this at model shows with the roof of the packer body off, so I will be filling in those open portions with styrene sheet to replicate the hydraulic tank shown in the sales brochure. This is also from the LP 900 sales brochure.  This view is from the front part of the packer body looking towards the rear of the ejection panel..... the sliding panel that pushes out the trash at the landfill as well as compacts the trash being picked up.  I will be cutting a notch in the ejection panel for the raceway and attaching it so that the raceway will stay in place with the roof off instead of making it part of the roof as shown in the brochure.      These are the inside of the packer body sides.  I understand to make the injection mold process work that AMT had to do it this way, but the insides need to be flat with no obstructions.  These raised parts would be disastrous in the real world.  I will be filling in the areas between the raised parts with styrene sheet to have a smooth interior of the packer body.  

Thanks!!! Just about got the cab wrapped up and have started on the packer,hopefully posting some progress pictures soon. 

The Ad Astra Modeling Club here in Topeka, Ks. had its annual show today......got a few truck pictures.... Fellow forum member and member of the Ad Astra Modeling Club, Paul, built this diorama along with fellow Ad Astra member Lamar Johnson.      Along with the logging truck diorama, Paul also built this fine looking combo.   A lot of scratch building went into this wrecker  

Thank you for the links my friend.  I completey understand your stance on youtube and agree that sometimes energy's are spent better on projects that count and also not disturbing workflow or area where this takes place.. I Also agree that Ads seem to have gone crazy on this platform and is very unfortunate for a lot of us as viewers that are just trying to gain knowledge and insight on the subject at hand and not filled with interruptions or pure rubbish that we are forced to intake.  Your Quote "I would much rather have a million friends than a million views."  is spot on!!  Thank you for your posts and insights and techniques and will be watching further progress with an eagle eye.

Shot this first light coat of color with the air brush....turns out there was cracks in the pick up tube...will have to sand out the areas of splatter and re shoot, other than that I'm o.k with it.  

I shoot a Paasche VL airbrush w/the 1 oz. glass jar.  After my last session, I went to clean the air brush and discovered cracks in the vinyl pick up tube that is in the glass jar.  
 1/8" I.D X 1/4" O.D micro fuel line (Red) One foot of fuel line cost me $2.00...enough to last me a long time.  
  As it turns out,the inside dia. of micro fuel line (gas powered weed eaters as an example) is a perfect fit over the fitting on the glass jar lid.  Instead of trying to clean the pick up tube every time I use the air brush,I will just simply replace the used pick up tube with a new, clean one.   

Mock-up for fuel tanks and battery boxes. 

Wow nice stuff!

I went to the annual Prison City Model show in Leavenworth, Ks. ...did'nt show a truck, rather a dirt track Gran Torino that garnered me a 3rd place finish in the competition class....enough of the car stuff.        This American La France 900 series pumper that pays homage to the 343 New York City firefighters that lost their lives in the line of duty on 9-11 won an award in the truck category...built by Brian Gauthier of the Show Me State Modelers....plenty of after market and scratch building.       One clean cab over.
