Tool , I am going to have to look into the Geil connection , as big as Greater New Orleans is I have never seen or know of a Gel dealer , Geil wheeled or tracked loaders are rare but do see a few all terrain loader/lifts , a Geil and a Mustang track loader was a Takeuchi with a paint job if am remembering right , I never paid much attention to the Takeuchi's coupler block but know that you say it , I am going to take another look , I have set a few up without the manifold for demo crews that were getting killed with broken couplers on the machine , made a bracket and used bulkhead fittings to mount the flat face coupler with the #12 straight pipe oring thread ( the one used on attachments ) , which is what I think Land Tech is referring to that he has , the models in between the flat face manifold and the old style were flat face without the manifold like I fab up , but it won't work out swopping it to a manifold block as the tubes don't line up ---- don't know if posted this story or not , I'm in deep depression wth the current recession , but I just went thru this one , grapple fork won't stay up on it's own , seemed like a piston seal , what it was is that the guy had changed a quick couple on the manifold and lost the guts behind one of the couplers n the block , probally without know it , as it will stay in place sometimes and sometimes fall out , without the spring and seat in there are misaligned it will flow oil over to the drain port and cause that problem and a few others -----I never really had a lot of trouble connecting aux hoses to the machine if I took the attachment off , that's a secret which is to make sure you got the pressure off before removing as pressure will be stored in the attachment making it hard to reconnect and it is easier to get a wrench and bleed the hose at that point , the new manifold will bleed if off it you keep pushing in on the coupler like you were going to connect it and give it a bunch of short pops in and you will hear the hydraulics clunk , as far as the machine the auto pressure release works , and if it doesn't release then , you can by turning the key on and energizing the aux curcuit use the thumb switch and release the pressure ----
