So the leak is at the 90 degree fitting where the fuel line connects into the head back by the turbo. It is not leaking where the line is connected but at the threaded 90. This was apart during the motor reseal. What sealant, if any, should be used or is the 90 just not tight enough in the fitting in the head?


It is leaking at the 9C402 fitting in this diagram

Thanks guys.

 

There just 1/8 pipe thread, prolly no sealant or not tight enough.

I've used normal old pipe thread tape without any leaks and that was 30K ago. Be carefully not to get anything inside as it will go straight to the injectors.

 

Pipe thread sealant compound such as Gasoila should work.

 

So I just now tried to remove the fitting and, of course the nut slid down to the fuel pump. Grrrrr. I got it back up where I need it but 1) to remove the 90 degree fitting and fitting in the head, do you just bend the line back a hair and 2) is that the "sleeve" on the line that I keep hearing should be replaced?


Thank you for your replies

 

I have never heard about a sleeve that needs to be replaced and I've been around awhile..

 

There are sleeves where the lines go into the fuel rails. When I did my e-fuel they both were almost disintegrate. My e-fuel system eliminated those lines but I do remember seeing how bad of shape they were in.

Thank you Hussler. Ordered from Riffraff.


Anyone,
Can the fittings be removed and taped with the turbo and fuel pump in place?

 

I believe the 96 and 97 trucks had a one piece fitting where earlier had a two piece fittings. The two piece fitting could be removed but the one piece fitting required the turbo to be removed. Since I had to remove the turbo to get the fitting out and install a new one for e-fuel I went ahead and ordered the turbo pedestal EBPV delete kit along with the free flow Coupler from turbo to down pipe. Glad I did, took me a day and half to remove the turbo and only 1 hour to install it.
