Where does this connect?

Bowana85 · Jan 6, 2020

I am trying to connect one end of a fuel filter to my injector. I
am not the one that took it off. Any ideas?

more info please and a picture. return line pressure line, tractor?

Roger Tomfohrde · Jan 6, 2020

Fuel filters go between the pump and the tank some where, not in line with the injector.

Fuel filter(s) go between the tank and injection PUMP. what tractor? pictures? Are all the parts there? Need more info.

Tab A goes in slot B. Best I can do without a picture or tractor info

Lack of info makes it hard if not impossible for us to help you help your self.

What tractor are you working on?? Also a picture would help.

With the info you give we can only guess if even do that

This piece was loose on the tractor seat.

Bowana85 · Jan 6, 2020

What tractor are we playing with?

How many lines, in total, connect to the fuel filter "head".

Note black nylon line going to bottom of transfer pump, likely from the fuel tank.

From transfer pump, line that's connected goes to fuel filter inlet.

If only two lines from fuel filter, the other line would take fuel FROM the fuel filter to the fuel gallery surrounding the injection pump pumping plungers, which would be one of the bolts with the bleed screws in them high up on the I.P., near the injector lines.

The loose line looks like it MAY be long enough to reach the rearmost of the two "bolts".

I wonder if it is long enough to accept the "banjo fitting" on the loose line?

It?s a Mitsubishi D4000.

To me it looks like someone replaced it with the plastic line.

(quoted from post at 13:38:11 01/06/20) It?s a Mitsubishi D4000.

What part was "on the seat"?

Is there any sort of port on the upper front face od the I.P., or the back end of the I.P., I found a couple of photos on the 'net that seem to show the feed line connecting at those locations.

that is the "injection pump", not the injector. the 4 injectors are in the head and those 4 lines on top the pump supply the fuel to them.
it appears like the filter is bypassed and you have a plastic hose running to the priming pump, replacing the actual fuel hose. follow those fuel hoses and see where they are going. got to have some kind of filtering going on there. who knows what some backyard mechanic has going on there.

What is the other end of that line hooked to??

Bowana85 · Jan 6, 2020

Think I got it! Suspected someone had altered the fuel line too, but it looked original and unaltered.

I had attached the first one inn the wrong port. Moved it and it looks right. If I?m not the one who took it apart I usually struggle.

I would like to replace this original strainer with a glass bowl filter.

I am missing the attaching bolt.

Once I get it bolted up an sealed off, can I bleed off the pump amp pump fuel all the way back to my fuel tank with the cylinder return lines by pumping it manually?

Dieseltech · Jan 6, 2020

I don't see a supply line TO the injection pump, is there one on the front of the pump?

Bowana85 · Jan 6, 2020

Picture of what I connected.

Bowana85 · Jan 6, 2020

I am missing the bolt part by my thumb! I am hopping it is not that hard to find

Dieseltech · Jan 6, 2020

That banjo bolt is either M14 X 1.5 thread or M12 X 1.5 thread, both use two gaskets on the fuel line banjo. MAKE SURE THAT LINE IS CLEAN!!! If not you WILL do damage to that inline injection pump, if not damaged already..

rustred · Jan 6, 2020

and your connecting that dirty old fitting to the pump!? pretty crude stuff. should have new hoses made up. just asking for more problems doing that.

Bowana85 · Jan 6, 2020

They arent connected yet, but thanks for the advise. I was out on a hill trying to get cell data looking at my iphone screen. I was working suppervising some dirt work and thanks to this forum I am getting some things lined out on this old tractor.

Who or what type of business would make up new fuel lines and have these connections? I am in a rural area in West Texas.

Bowana85 · Jan 6, 2020

Thanks Dieseltech

Just bought this project and know very little obviously. The seller claims to have had the injection pump rebuild, but it is obvious that some one did some work on it and was a little too heavy on gasket stuff on the pump.

If I can get a new or used injector pump if I screw this one up, I am playing with the idea of cleaninning up the injection pump. The governor is sticking and the engine is a runaway (I have been told). I am thinking about working on the governer in the injector pump. What are the chances of an novice being successful in your opinion?

Dieseltech · Jan 6, 2020

Usually when an inline pump equipped engine has "runaway" trouble, it's NOT the governor, but one or more stuck plungers CAUSING the rack to appear stuck. Dirty/rusty fuel like that line has inside, and other poor fuel and filter care can WRECK an injection pump. I won't hold my breath that you can fix it in the field..

Where does this connect?
