Fuel Accumulator Test Set

[Bitsyncmaster]

I made this up to test my old accumulator. I put an electronic pressure sensor on it but running air pressure into it shows it is bad with air flowing out the accumulator vent tube. Now I don't feel bad about cutting this accumulator open to measure the spring tension. From my testing of rest pressure it looks like it maxes out at 42 PSI and is empty below 30 PSI. Also want to see the size of the orifice.

By the way. The fuel accumulator uses one 14 mm X 1.5 cone nipple and nut and one 16 mm X cone nipple and nut which you can get from Belmetric.com. Most other accumulators use two 14 mm X 1.5 cone nipples and nuts. You can chose the size ID hose on the nipple. I see DMCH does not have the 16 mm and the 14 is a right angle to compression fitting. If our accumulators ever go out of stock, there are lots of double 14 mm accumulators cheap.
