Re: Bomb testing question

[spsherm@ibm.net]

A while back I was looking into a pump/bomb/etc problem and started
putting together an inexpensive pressure tester....

I went to a local hyraulics store (the kind that fixes tractor and earth
moving equipment hydraulics).  They had a gauge that goes to 3000psi
(and shows BAR too) for $22; an off the shelf item.  They were happy to
make up hoses that fit it, but they did not know about the metric banjo
fittings.  I picked up a used hose from the system at a junk yard and
was going to bring it to the shop to add a std fitting to one end to go
to the gauge, but before I did that the diagnosis of a bad pump came
thru from this list, so I never got to needing the gauge.

It seems that for < $40 one should be able to pick up all the parts one
needs.  Finding the banjo fittings was the hardest part though.  No Audi
dealer I spoke with was willing or able to sell me the banjo fittings
and washers specific to the test gauge.

Given the presures involved, I'd let a shop that makes up these hoses
make one for you.  Barbed fittings with hose clamps might work, but
given the pressures, and the mess and damage to a working pump that a
leak might cause...
