Question: Replacing Gaskets/O-Rings Under Fuel Dist & Throttle Body

[Tidybuoy]

I've got a couple of quick questions:

1) Going to replace the o-ring under Fuel Distributor. Do I need to do anything more than remove fuel lines? Basically, I don't want a bunch of stuff to pop out if I unbolt that thing.

2) Any weird issues for the throttle body - same situation as above?

3) Any issues with removing sensor plate (under fuel distributor) to replace foam gasket.

I'm just asking in advance of this weekend's project so I don't have any unpleasant surprizes.

Thanks............Vern

Sorry, I'm bumping this up to the top in hoping I get some advice. I'm sure I will figure it out but I like to get somewhat prepared before I get started.

Thanks............Vern

Why do you want to replace the O-ring? I try not to separate the fuel dis from the housing unless I actually have to.

The foam gasket is easy, just peel and stick.

Just unbolt all banjo bolts and have at it. Use new sealing rings.

Foam gasket, nothing to worry about.
Throttle body, nothing but vacuum lines to worry about.
Fuel distributor, be very careful around the plunger.
All easy, loosen the screws for the FD before pulling the sensor plate.

Don't drop the plunger on the fuel distributor.

Thanks guys!

I'm working on eliminating all vacuum leaks, replacing fuel lines, and general maintenance. This will help.

If your doing that go the rest of tbe way and throw a new air box in with the runner sleeves.
Might want to reset base co when done

I've already replaced all vacuum lines, injector sleeves & o-rings, runner base gaskets and runner large rubber pieces at air box, fuel lines, accumulator, check valve.

This weekend I'm adjusting valves, new WUR, ball joints, and a few vacuum leak possible spots (ie., orig post), fuel filter, plugs and oil change. I believe the air box is still good but a smoke test will tell.

I will definately adjust the co when done and after I've confirmed my fuel pressures are right.

This is going to be a good weekend

I'm assuming you have the engine or at least the Intake system off the car right now.
I would recommend testing the airbox with a regulated air supply, sealing off the ports and bubble testing with soapy water. (5-10 psi)
Much better than a smoke test.
Just duct tape off the holes and check the airbox seams for leaks.

I tested mine like this using the brake vacuum line port as the air supply point and found leaks.
