So I finally decided to build a pop tester. I've been wanting to replace the nozzles for a while.They are still the originals!!! :shock:
I took some pictures while making it so I thought I would share them. There are a couple good DIY's on the forum right now but another one will help clarify things a bit.
Nearly all of the parts, minus the injector line that was bought from Vincent Waldon, were purchased at princess auto.
Materials used:
2ton Bottle Jack
0-3500PSI Gauge
Steel hydraulic fittings rated at 5000 psi
Here you can see the entire contraption laid out. Note that I had to use two adaptors, one from the injector line to an awkward thread type I can't remember the name of, and then another one to NPTF.
Bottle jack with the safety release hole welded shut. This is the hole that prevents the ram from overextending.
Metal plate with fitting tapped into it.
Again.
Initial weld of plate and fitting.
Pop tester completed. I ended up having to really load on the welding wire. At first I had a few "weeps" of fuel coming out. Works great now!
Hope this helps anyone else thinking about making one. Not shown is the steel plate shield I made to prevent injury in case of any failure of parts.
If anyone has any questions, feel free to ask!
