They are building a house down the street,can see the pvc sticking up,will take a look,I think the actual horizontal piping is in the
dirt and not concrete,will take a look.

Getting back to the post,think if I ever redid hoses I would use the cover that Pierce talked about.
Question,we have the mechanical 8.3 with the mechanical fuel pump,runs great,have noticed when the engine is running the
bundle of hoses above the fuel tank make what I would call a vibrating thumping,it's only noticeable if you open the door,has
anyone else noticed this?

You can't possibly be serious, right?  The pipes are embedded in the floor slab?
I'm serious as a crutch.  This is standard practice for a site-built home...even today.  When they did our foundation, the pipes were laid out on the ground, and then kinda supported in different places by the wood braces and the rebar that reinforces the concrete.  Then the plumbing is buried under the concrete, which ends up kinda flowing around the pipes.  Makes it quite tricky finding the leak.  The water travels under the slab until it finds a way out.  In our case, it came up during the night in the living room wall 20' away, and flooded the whole living room.

SORRY I tried to derail the thread!  I HATE it when people do that!  :-X

Yes, I hear the same sound.  It is quite loud.  I think the noise is coming from the lift pump on the engine, and being transmitted forward to the fuel tank by the fuel lines.

I visited the folks at AD Hydraulics today to ask about putting the fittings on a hydraulic hose.

Very nice folks, very sympathetic to the situation we had.  Turns out that new hydraulic hoses do not come with clean cut ends but have some of the fabric rough and would make it very hard to attach the fittings.  So they, as we, need to cut the hose cleanly.  He used a cut off saw with special fine blade, diamond maybe?

I had asked about a tool to help one thread the fittng on.  Said no need, just make that very clean cut and then clean up the cut so there are no threads....in fact he said my panic idea to burn them off would work but a pair of scissors would do good.  He prepared a very clean hose end, then screwed the fitting on, using a wrench, lubricated the fitting with a little special grease.  Leave the fitting 1/16 inch from the hose being seated fully into the fitting, screw in the male connector.  He said the expansion of the hose by that connection causes a very strong attaching of the screw threads into the hose.  No need to worry about it not being as good as a hose.

I think Chuck said about the same earlier in this thread but I liked seeing it done.

This is common practice for ranch style homes in the west. Even in New Mexico, problems come up with the heated floor with some types of pipes, either plastic or copper. Our neighbor thought we had a spring under the house as water was flowing down the hill to their yard. I pumped cement into the old line, let it set for three days and ran a new one overhead and down the wall. No wonder slab/stick/drywall homes blow down so easily in a hurricane.
