Re: The difference IMHO Message #5 Posted by Dave,PLS on 1 Oct 1999, 9:52 a.m., in response to message #4 by DaveC
Dave, think about it. The material that hp originally used was a solid piece, the width of the axle of the driven gear. The cross sectional area of an O ring is a circle. You use a pair of O rings so now you have the area of two circles. The cross sectional area of the tubing is a rectangle. Furthermore, the contact area of the O ring is a small area tangent to the circle. Thats why you need a pair of them. I realize we are not trying to peel a bannana with this thing, but I think you see my point nonetheless.
As to the fuel line slipping, I have yet to find that happen. Surgical tubing sounds fine, that is if you have a source for it. The fuel line IMHO is rather indestructable, I suppose we could put a pair of 82104A card readers, one with my fix and one with the O ring fix on the dash of a volkswagen on 100 degree day for 12 hours in the sun and then see what happens. :)
