Fuel leak, over top of turbo, what is it?

[JCKnife]

Memphis Equipment has them for 61 dollars ! good supplier for Military trucks !

The O-rings or the whole nozzle?

My new one was purchased from Memphis. Check with air pressure before installing . Mine leaked straight through filling the crankcase with fuel !!!!

Why does the one I have recieved from memphis look completely different than the old one? Is this a updated version?

New design . No o rings to leak !!! Just be sure to check with air pressure before installing , my NEW design leaked straight through . This will fill the crankcase with fuel !!!

Well, I am little frustrated at the fact the compression fittings are not included. Also, with both reducers I installed I will have to extend the fuel line or get a 1/4" threaded 90. Then find a 1/8 female comp thread by 1/4" ntp. Maybe I'll get lucky at Lowes. I am kicking myself for leaving the old nozzle in Buford and not ordering the square o-rings.

So my newly purchased flame heater injector is dumping fuel into the engine. Time to call Memphis they can send me a new one and of course my oil needs to be changed.

Thanks for the heads though. It's just come on its brand new and leaks!

I see external leakage.

Is it just the fuel line fittings leaking?


Since your in GA, I'd simply remove the flame heater(costs about $5).

Mine was the same leaked straight through !! I added a solenoid valve and check valve to cure this problem .

Thanks for the tip, I checked and It's the injector. Here is a video showing the problem I ran into

So is is luck of the draw or do all of the new flame heater injectors lead? The very early flame heater systems had solenoid valves; are these "new" injectors designed for the early engines?

Mine was leaking through from the return line which has slight pressure when the engine is running . I installed a check valve on the return side and a solenoid valve on the pressure inlet side to be sure to control the leaking . It now works fine. New valve design is great with no o rings but sucks that it leaks through !!!

my heater was leaking also, i plugged off the lines to the heater and then developed a internal fuel leak into the crankcase. so then i ran the pressure line from the pump into the return line on the injectors. still have a major leak. any ideas?

 

[deathrowdave]

Just plug or cap both return and pressure line at the heater if U don't need to use it. U may be leaking at the FTD . Search bypassing the FTC and read posts on bypassing it .

Mine just started leaking too. Good thing I decided to start it and look at the engine running just for the heck of it. I didn't notice anything when I drove it a few days before. I may just cap it at the IP and probably just remove the whole setup since I've never had to use it in CA. It seems like more trouble than it's worth for something I never use.

The "LDS465-1 Troubleshooting Manual" shows the same hexagonal flame heater nozzle in a flame heater system with the solenoids. I suspect that it needs the solenoid to not leak.

What did you use for a solenoid valve? I want to keep my flame heater working, I use it here in Michigan. I rebuilt my original style nozzle a month or so ago, but I suspect a leak. I've got stuff leaking out at the joint between the intake manifold and the head, and running down the block. Still don't see how this thing can fill the crankcase, any fuel is leaking into the intake manifold, yes? If the engine is running, it should be pulled into the cylinders, correct?

I used a 24 volt solenoid 1/8 inch NPT on the discharge ( Small Tube ) and check valve in the return side ( Large Tube ) 1/4 inch NPT. These can both be found on Egay !!!

deathrowdave, any chance you can put a picture up of your setup?

Afterbeing unable to get the cap out of the rear of the original flame heater (until I got mad and drilled it then pulled it out with an easy out) I finally bought a new style one from Memphis and believe it must be leaking through also. I like the valve idea and would love to see what your set up looks like.

Working strange shifts again !!!! I will post pictures ASAP., latter this week on off day.
