New tank filler hardware from GBRJET
I would like to introduce a new set of filler hardware for use with a wide range of fuel tanks.
A while ago I struggled to find a filler unit which had a nice wide opening to allow a good sized clunk and associated plumbing to fit through, whilst there are some great products around I wanted to move away from the Dubro type units, and this is the result.....
Material: Aircraft grade aluminium
Fabrication: Hand made
Fixing: Hysol 9464 main ring to tank
Cap fixing: 6 x Stainless steel M3 button head bolts and washers (supplied)
Fuel seal: Viton O ring
Seal: Compression
Central hole thread: M6
Auxillary hole threads: M5
Overall diameter: 41mm
Internal opening diameter: 28mm
Weight: 30g (complete as in assembled photo)
Price: £28.95
The filler can be used as a feed plus two saddle/hopper tanks which fill through the two top barbs, or feed, fill and plug one hole or your combination depending on tank and fuel system.
Details are on my web site.

It glues on to the outside (assuming that I understand it correctly and it mounts like other metal cap systems).

Yes thats correct the base ring glues to the tank, it has a lip machined which drops into the hole made in the tank to give the largest possible surface area for glueing.

Scott, the barbs are the same as the CAT-M and CAT-L - 4.3mm ID on the pickup and 3mm ID on the fill/vent.
These barbs have delivered fuel to a P400 at NASA with no issues on restriction.

What connects to the overflow and fill nipples inside the tank in order to get them to the top of the tank ?

RE: New tank filler hardware from GBRJET
The unit has three points of supply/output, naturally the centre hole is designed for the pick-up to go to the pump and as such is the larger bore to allow maximum flow.
The other two entry points are for the modeler to choose the function, it may be feed from two saddle tanks, in this case the tank would require a breather to be fitted directly to its surface. The filler can be used so that one M5 barb becomes the fill point, and the second creates the vent, to make the vent I simply solder a piece of brass into the barb and bend it at 90 degrees cutting to a length that stops just short of the tank top surface when the filler cap is fitted. As the hole is large there is no issues getting this system (vent pipe) into the tank.
Hope that helps.
