Sorry for the bad question and confusion.  I'm finishing the 

plumbing on a custom fiberglass tank (not for a Europa) and 

am looking for general "lessons learned" for installing the 

AN fittings.



Did you simply drill the wall of the tank or fill neck and 

install the fittings with the AN nut?  Was any sort of 

hardpoint or bulkhead (flox or aluminum) used?  What about 

large washers?  Are your holes drilled net or are they 

tapped to receive the AN fitting?  Jos mentioned using 

redux.  Is that used on the outside to "seal" the fitting in 

place?  Any other "gotcha!"'s I'm missing?



Thanks for any info/tips you're willing to share.

You don't say how the tank is made. I guess it is vinyl ester 

resin/glass cloth but does it have a foam core?

I just drilled the tank, (polyethylene) then pushed in the AN fitting 

with a large washer each side and screwed on the nut. Warming the PE 

helps soften it to get a good flat contact both sides.

In your case something similar but using Redux420 or whatever they call 

it now, to form a fuel tight seal should work. You might try an O ring 

in a chamfered recess to seal the tank.
