Just a lost puppy trying to find answers here to a mechanic that jacked up my RV. I own a 1994 Fleetwood bounder P-30J Chevy 454 owner that i purchased from family fried and now we are hating it because we spend more on this thing then we are enjoying it. So we have thrown money at this a few months ago and had a mobile mechanic come to our home to fix a leak. Turns out this dip stick doesn't know anything about engines, Nor do I on a RV. So this guy un-threads this one aluminum line from what I think is called a hydro boost modulator. of course fluid spits all over the place and claims it to be a bad O-ring in side. OK, 5 cent part and puts it back together.. Starts the engine and still leaks. He takes it apart again and uses tephlon plumber tape to seal it. That's worked for a few days. Here is the problem. There were parts inside that line/flange that I believe go inside this line. When this guy cut out my tire shield to get to it, I don;t think he realized there was a washer, a spring and another type of brass washer. (see pictures) So he puts it together and leaves. I go to move the RV to the parking spot, put it in Park and the damn thing keeps rolling as if I am in neutral. Not to mention my reservoir that stores the hydro boost fluid to run the system has now overflowed all over the engine and onto the ground. this mechanic is now a fart in the wind. I think I found the parts needed to put this back together (see photo) i found this in the street where the RV was when I was power washing the fluid stain off the street. Does ANYBODY reconize these parts and how the go back together. There is suppose to be a spring as well that goes with it and I think it is still inside the flange. HERE is the main problem. I left these parts in my cup holder to my truck to take back to the RV. I had my truck detailed and now they are missing. I think the car wash guy sucked it all up with his vacuum. So now I either need to replace this line or find these parts so my RV will now stay in park and I believe these parts creates a one way check valve to stop the fluid from overflowing onto the floor as well as build up pressure to engage the Parking mechanism so I don't roll. Right now I have the RV in Park and I have to use the E-brake to stop it from rolling. Can anybody please help me on where to find these or buy a new one to replace. This hydro boost thing is in front of the driver side wheel well. I am pretty stupid to this being a first time RV'er and feeling like I should have stuck to a tent.. Only thing on a tent that breaks is a zipper .. LOL I am not sure how I can get the photos to you here. website is claiming photos are too big,, but on one picture you can see the middle steel line. That's the one that was leaking and I believe that parts go inside that line. Not the left or the right line. The steering column is to the right of theis module in black. I have tried all the methods to add arrows and save the photos to show you.. So I said screw it and posted in a public forum on my FB page. Here is the site. I hope this works, because I am desperate. Please be gentle as I am a first time Rv'r and I am about to set this thing on fire.. LOL so if you could SPELL it out for me when making replies so we have it broken down on a 6th grade level because I don't know the RV lingo just yet.
