RE: Europa-List: Re: Fuel coupling hoses at bottom of fuel tank

[Bud Yerly <budyerly@msn.com>]

Chris,

The hose over the fuel tank boss (which is about 1.125 inches) and the fuel
 fitting requires a hose that will stretch.  I thought perhaps you saw the 
stretched hose and figured it swelled from your original post.


The tank vent and filler area have been issues for those who fail to pay at
tention.  I've had to put aluminum tube in the 2 inch fuel inlet from the f
uel filler because guys cranked the clamp so hard they crushed the fuel fil
ler boss.  The vent and filler area of the module is normally cut conservat
ively without thought to fitting on the hoses.  The fiberglass has to be re
lieved to clear for the hose and clamps.  I have a drawing on this attached
.

The figure in the fuel tank section is misleading in my opinion.


Note:  it can be very tough to get one inch reinforced hose to slip over a 
fuel tank boss or vent boss.  But then again, thin hose can be attacked by 
auto fuel if not of proper specification.

Choose only after you look at the hose.  That is why I go to the hose suppl
ier and look.


Best Regards,

Bud Yerly

Thanks for the references Bud.


Thanks to all this feedback I think that my initial selection of hose was a
ppropriate. The swelling I am referring to is at the line between the plast
ic boss and the aluminum fitting. The fitting is properly in the boss. Why 
did it happen who knows. I will try to make a picture of it.


Will, not sure about you rquestion but here is a picture of the newly insta
lled vent. As you can see, the CM fiberglass goes around the boss. It used 
to be a little tighter and the coupling hose would butt against it preventi
ng from being inserted further in. I ground off some of the glass to increa
se the clearance which you can see the picture shows the hose further into 
the boss almost to the tank.


I think I will be fine. Will keep an eye on these components and if I have 
issues again will find some other brand of hose.


Best Regards,

Chris
