Impressive! If you don't mind, how much time did you spend identifying necessary parts, locating and purchasing parts, setting it up, and working out any kinks? And how much time did it actually take to setup and perform the test?I was able to construct a fuel return flow tester for my LMM. Rough cost about $45. I will try to post the construction details on the DIY forum.
Was able to test the flow rates on the driver side.
Will post results with passenger side bank when completed. Enclosed pix of test aparatus.
I try to factor the cost of time into any DIY project for cost benefit analysis. (build it or buy it) If not too bad, I may have to give it a try...especially now that you've taken all the hard part out of it when posted to DIY. Plagiarism is the most sincere form of flattery
Also, so what's the verdict on the injector returns? It looks like you have 3 bad because there is only one with the lowest volume. I've seen other test results were it was very easy to tell which were bad...two were almost level with each other and were the low mark...the others were all different volumes but all had more fluid.
