hey guys, yesterday morning on the way to work I thought I smelled fuel. I left the truck sit at work and when I got done in the afternoon there was a small puddle on the blacktop where fuel had leaked out. I drove home and it puddled again. I popped the hood and got a light to see if I could see where it was leaking.

It is leaking out of the return line off the injection pump. 1st I tried tightnening the banjo bolt and restarted. It still leaked. I pulled the bolt out (which has a ball check valve? in the end) and flipped the metal washers. Put it back together and it still leaks. It is coming from around the return line somewhere. I don't know if it the return line or not, but I'm stumped. Fuel runs back the line then drips.

Don't know if anyone has dealt with a problem like this, but I'm open to suggestions at this point.

Thanks

Scott

 

Go get yourself some new washers and a check valve to start off with. Have you changed VPs' recently or had that line off?

 

If I were a bettin man, I would say to check the banjo bolt on the back of the motor block. I bet it's lose and fuel is runnin downhill along the line till it hit's the pump and drips.

You have a Banjo on the back of the block and another where that lines comes to a T and intersects with a line that is the injector overflow, check this also.

If you haven't pulled the Banjo from the pump lately odds are against it just suddenly developing a leak unless it worked lose and you said it was tight. Also be careful not to over torque those things or they will leak.

 

VP44 was changed about 3500 miles ago. Everything was good until yesterday. You can actually see fuel spraying from where it is leaking. Only problem is you can't see where it is leaking - does that make any sense?

 

If it's sprayin are you sure you don't have small split in the hard line. Vibration does this once in a while.

 

It is actually spraying from around the area of the return line out of the pump.

Pump was replaced about 3500 miles ago, guess I'll try some new metal washers next, but they were new with the pump. I'll look at it closer tomorrow in the daylight

Thanks for the help so far guys

Definetely something I will have to check out. Makes sense that it maybe a crack. I actually drawed them down kinda tight. It may have made it worse.

 

Hope for the best, that's an expensive little line there. If it is split, let me know before you buy another, I may still have mine layin around someplace.

 

Go ahead and see if you have it. I will have to let you know. How expensive do you think it is?

 

Don't remember on each of em but all the hardlines are pricey. I did away with all mine and used high pressure line for al of my system. The flow regulator banjo on the pump is the only stock piece left and it connects into high pressure fitting. I'll look around for it tommorrow and let ya know.
