Hey folks,
Does dms have an ultrasonic cleaner suitable for cleaning out fuel injectors?
If not any local shops that you guys can recommend?
I also need to renew some old fuel hoses, and they have some crimps and ferrules at the end that need to be salvaged and reused. I’m told that hydraulic line shops are the best best for this, Any suggestions in the local area?
Or perhaps there’s a little known shop that sells these items for reasonable prices? While the parts are available from various specialty shops, it’s shocking prices like about $350 - 400 for the set. I reckon I can buy generic FI hose and reuse the existing metal bits
Not to derail your question, but have you priced new ones? I doubt it’s worth trying to salvage old fuel lines.

He’s trying to salvage the metal ends, which, depending on availability is perfectly normal. I’m assuming this is for the Jaguar we were introduced to here Tracing AC leaks
It doesn’t really matter. Most NAPA stores and NAPA retailers will do it, as far as I know, as will virtually any hydraulic shop. I’m sorry I don’t have specific shops to recommend, as I haven’t done any of that stuff since I lived elsewhere.
For what it’s worth, I’ve never seen the individual injector hose ends saved. Most folks just put smooth clamps on them (I’m not advocating it, I’m just waying that’s what I see).
EDIT: Here’s a web page that goes through a process similar to what Sonny’s looking to do, presumably.
And another doing the same thing to a Porsche 928. Difference is, though, they don’t include the big pieces of long rubber with crimped-on metal pieces between as shown in the upper picture, which is, I think, specifically why this question is here…
@jast, you have it right, reuse the existing metal lines and ferrules if possible, while replacing the perished rubber with standard auto-parts fuel hose. On the injectors, new ones are $27, whereas replacing the metal screen, O rings and pintle cap is under 10 bux. On a 12 cylinder car, it adds up. I expect to save over 300 bux doing it this way.
Do remember to make detailed notes and take pictures if you are assembling hoses that include more than one angled rigid piece. If you do not get the ‘clocking’ right the hoses will not fit and you get to do it over again.
Sonny:
This is a simple yet effective fuel line crimp tool (I used to have something similar ages ago when I worked on factory fuel injection systems(Bosch systems starting in the 1960s) that used those crimped/swedeged hoses)
This could probably be duplicated at the Space but for the $35usd it probably wouldn’t be worth the time invested…
Looks like good info, Tom!
Got me digging around a bit more, and it looks like this is much more popular amongst the British motorcyclists. Here for example is a place selling sets of 4 ferrules for classic BSA Triumph, Norton, etc. bikes. Here is their tutorial on using it.
And of course, here is their version of the tool.
It looks like Summit sells “crimp collars” which might work as “ferrules” as well… Here’s a specific one (they mostly want to sell the “aeroquip” stuff, it seems).
I’ll stop now. Sunny’s probably at least as proficient with search engines as I. Sure be curious to know what you settle on…
My brother had a classic Triumph Bonnevile when I was kid - most would have never thought Triumph would return to the US market…
I’d like to see a good to high quality die crimp / swedge / swag fixture at the space at some point for fuel / hydraulic / refrigerant / vacume lines etc. (Not harbor freight or Northern Tools crap). I used to rebuild hoses by re-using the existing ends. (way back in the 1980’s some Mercedes models used AC lines to cool the fuel going to the engine via a multi piece refrigerant line / fuel cooler and when one typical hose area started to leak the new hose was cost prohibitive so I would replace the failed rubber and new ferules, die swedge, install and reduce the time and end cost to the customer).
A tubing / brake line flaring / bending tool like the one sold by Eastwood would be great for tubing as well. These would be not just automotive specific either.
Curious if you got this all fixed up, Sunny.
I ran across this today, looking for a way to salvage some air hose fittings, and it made me think of this…
