Hi there.
I own a Series II Land Rover that has at some point been fitted with what I was told was a 2.6 Isuzu diesel engine. The chap didn't know what specific vehicle it came out of, but anyways.
Recently I was experiencing a problem where I would lose power suddenly and the engine would die. So I checked the fuel filter and the previous owner had put the filter canister back on with NO filter element in it, so the thing was sending whatever filth is in my fuel tank straight on to the injection pump.
So, after fitting a new fuel filter element and cleaning out the lines I'm still having the same problem and so I'm wondering if the injection pump has a gauze filter on the inlet pipe or somewhere else. I had a quick look but haven't been able to see anything obvious, but I'm not very familiar with diesel engines, so this is all new to me.
I was hoping you could find it in your hearts to have a look at these images of the injection pump and if it is in fact an Isuzu fitment, and you're familiar with it, share some of your knowledge and help get my Isuzu-powered Landy back on the road.

You don't say specifically what model or year so I am going to take a stab at this. Going to assume you have a 2.25 diesel unless you have the safari wagon which was the only one with a 2.6 in the Model 2A. Still convinced it's a 2.6 look and see if it has a Westlake cylinder head. This is a very cool vehicle (nice find) <img src="/forums/images/graemlins/cheers.gif" alt="" /> Only 88's (109) Safari Wagons were available (export) from 1968 to 1974.
The 2.25 shows a primary and a secondary fuel filter. I will need to resource some material on that Kiki Bosch pump - if I find something I will report back

Good Luck

Ommony - found this tidbit while looking for pump configuration:
" Some Rovers have an water and dirt separator mounted on the chassis rail on the rear in one of the dirtiest positions on the car. It augments your main fuel filter's life considerably. It must be purged once a month. Wear plastic gloves for this. Simply unscrew the wing nut at the base and let the mixture flow out into a small jar. If water is present you must repeat the purging daily until no more water is present. Then you can return to a monthly purge."

Maybe worth investigating.

No no, you misunderstand. My Land Rover doesn't have the original engine, it has (I was told) an Isuzu engine. 2.6 Diesel. The KIKI injection pump would seem to confirm that it is a Japanese engine, at any rate. But any further than that I'm not certain.

The sudden dying does sound like a fuel loss. So I think you are on the right track. The pump is a version of the
Bosch VE series (as built by Diesel Kiki). I have worked on a number of these at the fuel shop where I work part time although your particular pump I have never seen. But the fuel inlet is at the banjo fitting near the front of the pump as seen in photo number one. And, sometimes these do have a guaze strainer built into the banjo bolt or around it.

Also, some vehicles have a guaze filter in the tank and this is an insidious place to have a fuel blockage.

If these places look OK I would put a low range vacuum guage in the fuel line at the inlet of the pump and look for less than, say, 50 mm ( about 2 inches)of mercury negative pressure when the engine is running. Much more than this and I believe the VE pump would have problems lifting the fuel into it's body.

Another possibility is an air leak in your fuel line which in some cases can let air in without any fuel leaking out. This can starve the pump to the point of killing the engine.
You can test for this by temporarily installing a clear plastic line at the inlet of the pump which will allow you to see air bubbles when the engine is running. Should be none or next to none.

Also, this pump has an electrical solenoid which must be working to enable the fuel flow in the pump. This is usually located on the top of the distributer head at the rear of the pump, although I see a solenoid on the top cover in photo number one that looks like it. But this could be something else. So look on the distributer head for a similar solenoid.. With the engine off, you can disconnect the wire to it and then touch it to the terminal (with the key on ) and you should see a small spark and hear a click. If you do, this should be OK, although it could be intermittent.

Hope this helps-- Paul

My money is on what Paul suggested. And on my engine the fuel inlet at the front of the pump does have a strainer in it.

Check there, I'll bet you'll find it gummed up with crap,

I had this problem once with a diesel Jetta I had...MAN, was it tricky to find. I put the clear plastic line in the return line, and found air, then no fuel returning, the motor would die out, then mysteriously start pumping again...finally traced it to where the fuel line hooked to the pump. Seems the line has another line over it (likely to reduce flexing and fatigue), and after 10 years the hose swelled a bit and sucked air in where it slid on the fitting. Nothing ever leaked out, just air in.
I cut 1/2" off the line and problem cured!
