I've often wondered if a pressure gauge reading the internal IP pressure would be a worthwhile thing to know. I reason that it could be fitted under the return banjo with special adaptor. Has anyone had similar thoughts, done this or recorded readings?

Re: Internal IP pressure test gauge
not actually under the banjo bolt but through it.
I liked the idea of the grease-gun hose to connect the gauge. Seems the pressure is somewhere around 100 - 150ish, so needs something that won't soften, melt or otherwise fail.
The pedestal bolt I like the look of is as below. The male thread on the left screws into the IP, while the original banjo bolt screws into the female thread on the extreme right. The brass fitting runs to the gauge. With this set up, no modifying original fittings is necessary.
When I get a minute, I will have a crack at this. I have a spare IP on the shelf so can do the leg work first, then swap it out.
The stock spec for pressure would be good to know and I don't have it. Google can't find it either. Mine is a Hiace 5L 3Litre '98 should any reader have the info, thanks.

Re: Internal IP pressure test gauge
Looks good, do you have that fitting or is just a picture of one at the moment? Yes I want one.Johnnojack

Almost everything I have is BSP, imperial.
That pic came from the VW web pages.
May make one, but might check a few junk yards out first.

Re: Internal IP pressure test gauge
Have found a new nut with correct 1.5 thread which I could use. A friend is fairly confident of finding a tap. Also found a IP banjo bolt which I could possibly use as the donor for the male.
The wheel stud idea is a good tip too and have lathe in the shed.
I have a metre length of high pressure grease line with fittings on it.
A gauge is something I might have to look for. Any idea on PSI range of a typical IP? Am thinking 150ish?
Next week something might show up.

Re: Internal IP pressure test gauge
I got the adaptor finished today and run an old remote grease line to a gauge. What a mission getting to the return banjo!
Next thing was the old grease in the line. The pressure wasn't enough to push it out....eventually got it clear.
Top pressure recorded so far is 40psi, with idle 15-20. I think it will be a permanent fixture due to the difficulty with the access.
So, anyway I will test over the next few days...

Re: Internal IP pressure test gauge
Excellent I'd really love to know if the pressure changes when you switch to vege oil. Can you note the temperature of the vege at the same time when reading the pressure if that is possible.Johnnojack
