RE: [DML] Re: Buiding Injector Testor/Cleaner.



I would consider using an air compressor with clean, dry air, tied to an
AC flushing canister similar to this http://tinyurl.com/5rtnqv and adapt
the fittings...

That's a very good question. Let me explain:

As of right now, the only person I know of that cleans injectors is
John Hervey. Now I've nothing against him, I've bought many products
from him, and he's been a big help. I just that with everything I
have, it's more cost-efficient to build this rig on my own because of
how many injectors I have to clean. Plus I've had problems with dirty
injectors in the past, and with our lack of a proper DeLorean mechanic
here in town, I take comfort in building up my tool collection.

Other garages around town want to charge me a labor rate equivalent to
his, so once again I'm in the same boat (though John appears to do a
more thorough job, no to mention I'd trust him more). Now we do have a
BOSCH supplier here in town. And they do have a tester/cleaner. But
it's been broken since 2000, so they don't provide the service any
longer.

Now I know I can build one of these, because I've seen how others have
built units made for Diesel injectors:
http://tinyurl.com/6cxfzq

The problem however is that these bottle jacks are running at diesel
injector pressure levels of 1,800 or so PSI, and I only need something
around 80 or so PSI for gasoline. And to further that, I'd prefer to
get a manually operated hand-pump rather than an electrical one for
safety & simplicity. Although eventually I might just use a spare
K-Jet fuel pump to run a flow tester I've thought about building.

Now the thing is, and I'm hoping that perhaps someone can shed some
light on this for me, is that I don't know at what rate these
hydraulic jacks pump at with a single stroke, and no pressure against
them (first stage, I believe). If it's around 100-150PSI on a single
stroke, then I'd be safe to use one of these for K-Jet, because the
injectors would pop-open as soon as the pressure built up, and would
bleed everything out.

I know it seems like allot of work, but it's a tool that I'm willing
to invest in for the future to complement the other specialty tools
I've bought/made for the DeLorean over the years.
