Having an issue installing my new Delphi Fuel pump. I cannot get it to seat in the tank. I can get it close, but still a 1/8” gap between the top of the pump and where the lock ring needs to go. I don’t want to add anymore pressure because it’s plastic. Any advice on this, what am I missing?

MSD box maybe? Might be cheaper than buying all the stuff needed to program an EPROM.

Anyone know off hand if the drop on this Air Cleaner will fit without interface with anything on 89 tbi? Like to remove my chrome one thats on it. AND why do some of the filter elements say for carbs? some for TBI?

It may hit the top of the coil wires, a flat one worked on mine.

Seen one here on a smaller motor video, Like it better than my chrome one.

Here's the one I have, I bought it with a drop bottom, ran it for a while. Then I noticed it bent the coil control wires. I was afraid they might short out and leave me stranded so, I bought a 14" Moroso flat base, now I have good clearance.

I got new wires and connectors to replace the bent ones. See how high the connectors stick up? IDK, it may be because of the Edelbrock 3704 intake manifold too.

The coil wires on yours look new? where did you find those? Mine are to short.

Yes they are - the one with the plastic harness (I added), I got at O'reilly (I think) but, I don't have the p/n. Here's the original one.

Here's the other one I have listed in my build sheet. You may be able to find the coil to ICM one there too. Michigan Motor Sports makes a lot of harnesses, including the 1 to 3-wire O2 sensor adapter.
