Aluminum Fuel Tank Caps
with 5/32 soft brass tubing

NOTE - Aluminum Tank Cap Fittings purchased during 2003 have rubber stoppers that can deteriorate due to additives in the gasoline from some states such as California and Indiana.

The black rubber stoppers purchased from BVM post January '04 are ok. Of course, BVM will replace any problem stoppers at no charge.

NOTE - There is no problem with any black stoppers using Jet-A or Kerosene fuels.

Here is a fuel tank cap system that will not flex and deteriorate with time. The machined aluminum cap and threaded disc capture the standard rubber stopper and squeeze it securely with a 4-40 socket head machine screw. Results are a leak proof cap, even when pressure is applied to the fuel system.

The 5/32" diameter soft brass tubing allows freer flow of the fuel as required by some of today's larger engines.

BVM uses this system on their ducted fan installations as well as for turbine fuel systems. Other specialty enthusiasts will surely want this fuel system improvement as well.

Each cap system contains one rubber stopper for use with glow fuel and one compatible with petroleum liquids, adaptable to Sullivan or Du-bro tanks.
