I Was Also Told

So darned cold outside this morning that the cat won't even stay out!

Anyway, I just remembered something the local "Red Mech" told me yesterday when he was explaining the 966 injection pump "hazzard". :>)

He said that hose coming from the final fuel filter to the pump had to be replaced because someone along the line had put a generic fuel line on this location. He says this is a sure-fired way to ruin a good pump in time.

He says when you kill the engine, that the fuel in the pump is still moving and the abrupt 'stop' is akin to shutting off a water line real fast and getting that "banging of the pipes" noise.

Says the hose has to be of the exact length, made of the correct materials and be of the proper diameter and thickness so that it will flex and "absorb" this sudden 'thump'.

Further, that this is a 'harmonic effect' and that this generic hose, which is on there now, is hard on the pump.

Found that interesting,

No, not on the secondary side.

This is the rubber-like hose coming from the filter to the front of the pump.

I don't know if this is a return, a feed, or what, but like Cowman says, when the tractor is running, it is definitely under pressure because it actually "throbs".

Sorry for the bad picture, only one I could find.

Yes Sir, that is exactly what he said.

If the hose is wrong, it could cut power on one hand or use too much fuel for the given horsepower on the other.

Does your dad still have that 1066 that they stroked out to a 1466? That tractor is kind of a legend around here and I still hear people talking about it from time to time. :>)

Aw, I'm such a picky ol' fuddy-duddy; everything has got to be 'just right' and on a normal day with a knee-jerk reaction, I'd just go ahead and put on a new pump without givin' it a second thought.

But since this whole 'scheme of things' is nothing more than a over-sized hobby and is not critical to my business to any great extent, I'm gonna leave it alone. The tractor can certainly be down for a period of time in the future and it won't pull any skin off the end of my nose.

I just like to bounce these things off of you guys with your experience; there is lots of common sense hangin' around here.

Now, if I were depending on it everyday like Cowman, Todd, Captn' or a lot of the rest of you, I'd most certainly put her on there, just to ward off a break-down.
