Pop tester recommendations?

[Phil01]

Hi all
Can anyone recommend a decent pop tester that won’t break the bank? I heard good things about this BGS technic | Injector Nozzle Tester | purchase online - [Leaving Land Cruiser Club]

But at €500+ it s a bit beyond budget. And the lower end ones mostly appear to leak and need rebuilding.

Unless you are doing loads of injectors is it not more cost effective to take them to a specialist who will have an expensive reliable tester that is calibrated....

There's this one Injector tester , still pricey but as Grimbo has said, probably better to entrust them to a specialist if it's just foe a one off.

TBH..... I change a fair few injectors and fuel pumps and for me it's easier and more reliable to have them refurbed by a bloke who's business is doing just that...
It's not fool proof as I found out last year when a brand new FIP that I fitted refused to let the engine run properly... it was an arse to access because the tractor had a loader so I assumed I must have got the timing wrong ....removed pump and sent it away for retiming as it's the type that's locked by a bolt ....refitted and still wouldn't run .... removed a 3rd time and sent back to supplier who in fairness had just ordered it from Delphi and sent it to me.... they ran a full test of it and found the brand new pump was incorrectly set . Fitted it and the tractor started and goes like a dream now .
Moral of the story.....never assume because it's new it's correct .... the supplier now at their cost checks all "new" pumps from Delphi before despatch

A bit of useless info here, but I did my apprenticeship at Hartridges in Buckingham, and my first few months were spent on the pop test section putting them together. That was back in 1980

Thanks for the link Towpack.

Yes it occurred to me, and I suppose you’re all right about a specialist but it s that “enTrust” question, and overcoming my delusions of mechanical grandeur!

Do decent specialists usually give you an analysis or print out or something?. I really want to see for myself what the current injectors are doing and how the new compare.

All things being well, another 10 injector services at 100k each isn’t entirely out of the question. If, as I I understand, injectors are “relatively” easy to service. I can practice stripping and redoing the old ones until I achieve consistency.
Any idea about how the testers are calibrated?

I would imagine the gauge is calibrated in psi or Bar or maybe both. I watched an episode of the Wheeler Dealers program where Edd China used a very similar device to test the injectors on a Merc. Basically just operate the handle and observe at what pressure the injector fires and the spray pattern it produces.
