Gents
I'm in the process of making up the water (or hopefully just fuel) drain
mod for fitting to HI. I've made up the finger strainers and the manual says
that they can be soldered or reduxed. I tried to solder them but couldn't
really get the gauze clean enough to solder well enough that I was happy
there wouldn't be bits of solder wandering about on both sides of the Gauze.
I acquired another piece of gauze from Europa and this time, reduxed it
along the seam and around the end where its pinched onto the copper tube. My
question is, after soaking the unit in petrol for about 6 hours, the redux
doesn't appear to be 100 percent fuel resistant as it seems to have softened
(it was given about 72 hrs to cure). Does anyone know if Redux is OK for
permanent immersion in Mogas?
Thanks
Peter

I just pulled a tank out of an 8 year old Europa with Redux/Araldite/Epibond 420 A/B and it is holding up very well.
10% Ethynol Mogas can soften the outer layer just as it does most sealers like Pro Seal C and the bond still holds at a 10% ratio. Keep in mind C that Redux cured below 75F or until a full week will not be totally cured C but will hold. Huntsman produces product data sheets with characteristic reaction to chemicals.
My tests in the shop use the Redux to hold various acrylics/urethanes to test for fuel tubing C and the Redux holds up perfectly for me in a week long test.
As for soldering C I use a scotch bright cleaning C flux and a torch to solder C just like I do with copper water supply lines...No problem. But I always use Redux to seat the gauze in the fuel fitting.

Peter - off the top of my head, I seem to recall about 5 days at 25C
is the recommended period for full-strength cure of Redux. Maybe
yours hadn't really cured before you put it in the fuel. I think the
manual does say something explicit about doing the bonding-in well
ahead of time so it's really well cured before being exposed to fuel.

Rowland

Thanks everyone for replies - I'll dry them off and see if they will
cure after exposure to fuel or if its time for another piece of gauze.
Regards
Peter
