The machine started running real bad with no power. Changed out the fuel filters and all was well for about 5 minutes. It then started stalling. When it dies. You cannot immediatly restart it. But if you wait 5 or 10 minutes it will fire back up and run for 15 seconds and die again. I hooked a 1 gallon jug of clean fuel to the pump and it will run fine untill the jug empties. I wouldnt think i have already plugged filters after 5 min of running. But i cannot find any problems with the lines. I drained a couple gallons of fuel out of the tank and it looks good. I have noticed that when it dies i can open drain on back filter and hear it suck air. Any thoughts or ideas will be appreciated

 

Tank vent? Is the fuel pump mounted on the front of the engine like bigger cat engines?

 

Tim, I think you nailed it with the tank not venting properly. This is a perfect symptom.

 

Or a rubber fuel line collapsing somewhere?

 

Seriously enough, I have had everything from frozen/plugged vents to dirt/leaves/branches in the tanks,to my personal fave so far, 89 international fuel truck, where the departing driver took care to shove a whole book of meter tickets into the fuel tank. Talk about fun cleaning that up, once we found the problem.

International trucks. 13 letters that spell pure misery... then add a driver.

 

HEY! I like Internationals! Simple, comparatively cheap, and reasonably durable. Cats on the other hand...

 

You spellet it rong Pind, its Intertrashonal.

 

The only good thing international ever made was a manure spreader and even they wouldn't stand behind that!!

 

Ouch

Hey, in newer class 8 trucks, I have to defend international. They make a pretty decent unit for the money, with a large quiet cab and good forward visibility. Not at all like those chached out petercars and kenworths. Nothing better than finding a comfortable position, then looking directly into the overhead console......

Besides, when farmers retire, they need SOMETHING to drive.

how about the original fuel problem?

 

Caterpillar has issued a service letter concerning fuel transfer pump failures on the E-Series backhoes. I wouldn't say it is common for one to fail but I have changed out several in the last year.
Pull the LH panel off of the engine compartment, disconnect the fuel supply line to the IP and run it into a soda bottle. Bump the key to the start position and the pump should fill a 20oz bottle in less than 10 seconds.
If you have a lot of foam or a slow stream, either the pump has failed or the inlet on the fuel filter base is clogged.
If you can give me the backhoes serial # I can get you specific information.

 

Now THAT'S an answer!

Why couldn't YOU do that Pind? Or Tim? Instead of making fun of a very good truck!

 

I still dont think its a pump problem, however with no updated information one can only wonder.

 

wonder wonder who, who wrote the book of loooove???
