Thats a pretty nice unit that he came up with over at **************.....I may consider one in the future..... it practically costs that much to have a shop do a set or two of injectors....so why not have your own!

Last week one of the members posted how he/she made one from a jack similar to the mercedes source one.
I found the thread: http://www.peachparts.com/shopforum/showthread.php?t=224334&highlight=pop+tester
His homemade pop tester I believe is better than the ************** one as I do not think the ************** pop tester had a valve that cuts off the gauge.Though this valve is not 100% needed it protects the gauge when you want to do some serious pumping on the tester handle.
Perhaps he could be prevailed upon to produce some more for sale

I actually just ordered their pop tester to do my injectors.

C Sean Watts is also his member name. Go to the top and do a search and when you find him send him a private massage.

Got lost in customs - resubmitted. I appreciate your patience and patronage.

I saw several places where you can buy Monark nozzles online for around $25 each. Just google it.

Cool....I shall look into that if we do decide to do a nozzle swap on the ones we have for the new motor.....we may get them tested first to see how they are currently.

C Sean Watts · #39 08-03-2008, 07:31 PM

They have arrived!

Good news! Yes, there are others selling them but I prefer to support an active member on this forum.

10k on my monarks now. I must say i am not disappointed with my decision. And now that i actually have boost again, what a difference. Seems the pop off valve line had a hidden crack. Not bad for 24 year old rubber. Runs better than ever. Definitely sold on monarks from here on out.

I also like the Monark nozzles!

The 87 Mercedes 300TD I recently got had service records for the last 80k miles, now at 243k. Nothing in them about injectors. So I pulled the injector nozzles, tested on my homemade pop tester, they were all near 1900psi, just below the low end of the recommended 1957psi. They sprayed a solid stream, not a cone. They were made in India bosch nozzles. I replaced them with new made in Germany Monark nozzles and pop tested the set and boosted the pressures to 2100 psi by adding shims, to the high end of factory specs (135-145 bar). These nozzles make a much better looking spray pattern. it made a large difference in power at all RPMs but especially off the line 600-2500rpm, smoothness, less smoke, and quieter at idle. And I thought it was very quiet and powerful before this!

Here is my homemade pop tester made from parts I bought used on ebay (like a portapower), a 3000psi guage, an injector line for free from a junkyard, and a clear salsa jar it sprays into:

Thats a really nice Porta Power setup you made. Could you give us more information? What size unit you used? Cost? Any other info that might help recreate one like it? Thanks in advance. Great job btw. Jim

I started a new thread about the pop tester here:

The Bosios nozzles i bought were made in italy, NOT india..I double checked.
They are performing great after 9k..but a lot more money than these monarks,
at the time, i never heard of them. The italians are actually in the same league as the germans when it comes to machining--thats my industry, and I am not italian.
