Broken Fuel Test Port

[Janimal444]

I broke this a while ago and have had a machine screw temporarily screwed into this location. Starting to get a knocking injector, I am sure it is related to this, probably time to fix this legitimately. I know I can plumb the fuel line directly to the CP3, but seeing as I do not have a factory fuel filter I kind of need this location to bleed air after fuel filter changes, etc. Exactly what part do I need to buy to replace this fitting (it broke at the narrow aluminum shaft). This is not cast into the head is it?

I had a machine screw with Teflon on it for like 3 years no problem lol. Those things break easy

I've never had to bleed anything after getting air into the lines, the lift pump pretty much takes care of it. Are you certain you actually need to bleed the air out? I would just ditch the whole thing and take fuel straight to the CP3.

I have the Kennedy dual pumps, I did have to prime the fuel system after my injector swap and after last filter change. Although on the last change I did not fill the new filter with fuel, I assume that probably made a bigger difference than I thought? I just don't want to end up with no way to bleed air in the case that I need to. If I have no stock fuel filter or test port will there be any way to bleed air?

My main question is, what made you decide it wouldn't start without being bled? How long did you crank it for, or did you just go straight to letting the air out? Sometimes I have to crank it for 15 secs or so after I've opened the fuel system, but I've never had to bleed any air out once I had a lift pump.

with my Kennedy pumps and dual remote filters, it would not self prime/bleed for nothing. i tried and tried cranking on mine and couldn't ever get it to fire without bleeding the air out

Much like Trubbs said, I had to crank it for 30 seconds at a time, several times. I had no luck, so eventually had to bleed it. I suppose in the worst case I could re-install the factory fuel filter in a different location (I have twins) so that I have a way to bleed the system.

You could always add a valve in the middle of a rubber line to bleed the air.
