BVM Mig.15

Afternoon Guy's
Next job is to make up the fuel tanks, consisting of a left and right saddle tank and the main fuel tank. Each tank will have the standard set up of main feed clunk and overflow vent. For those not familiar with using multiple tanks I will give a brief word on how they are plumbed together. The main tank will have a pipe fitted on the overflow going into a "T" fitting which in turn then fills the two saddle tanks through their main feeds and saddle tank overflows are plumbed together via another "T" fitting and exits the bottom of the fuzz, hope that makes some sense. The main tank which is filled first can be of any size but the saddle tanks must be the same capacity so they fill and overflow together.

P.S Don't like the look of the supplied clear plastic fuel tubing so will swap for the tried and. tested yellow tygon

Coming along nicely Pete.

A lot of fiddly work though. JRI should recommend you for a Knighthood after this. :lol: They are giving them away to easy nowadays. No reflection on your abilities but you know what I mean after the New Year Honours list saga

Looking good Pete, keep the updates coming

The tanks are ready to have the fittings installed. A good tip when fitting the vents on this type of tank is to cut a very thin slice of tygon which acts as an excellent fuel tight washer.
I've mixed up a small amount of hysol to fit the main feed inner fittings and smoothed round with my finger to make a nice joint. Hysol is slow setting so will be left overnight.Once cured the tank halves will be glued together with hysol and left to cure,klunks fitted, filled with fuel to leak test.

If anyone is thinking of using hysol make sure you use the aeropoxy. You will probably have noticed that I'm using BVM aeropoxy in my gun same stuff but rebadged so they can charge you 4x as much
