Arrow '86 SDL fuel filters

First, is the attached picture 'normal'? I know it looks fine for a gas filter having the air in it, but I don't know about diesel, as my ford has no little primary..

I replaced the primary and secondary filters. I started with a different primary than the attachment. It is a reusable glass filter I have many refils, so I thought it would be good to use encase I had some in tank problems since I am new to the car and it has sat awhile...

Here is a video of the poor results;

Now THAT has to be wrong. This filter screws together so you can change out the guts. It has four different places it goes together and so I decided it was just to risky to use, too many potential leaks.


Off to the store and I bought the official wix filter, put it on and I think it still leaks? First attempt but it dies;

This time I try to hold a higher idle to show more bubbles... I held my hand in the same position throughout, so it should have remained steady? It would have died at the end but I 'feathered" it a bit. I also hear a high pitched tick that I did not hear with the first glass filter.

This time I have let it idle for at least a half hour. I was hoping that the air might dissipate?? Anyway, again I hold the throttle as steady as I can in one position throughout the video until release at the end and it dies..
It can be hard to see but the level of fuel in the filter is dropping...

As to weather or not there air in it before I started messing with filters, I don't know. When I got it, it had no primary..

I have read allot (every post in this forum that had sdl in it) and so I have some idea what is going on, but I cannot KNOW because I may be able to read all day long, but it doesn't give me any experience.

So, my theory on hat I have read is that this is NOT OK and I have an air leak somewhere between the primary and the tank.

I have a receipt for

6/10/7 Fuel hose return line, in-tank hose, filter, screen

The metal fuel lines cannot be rusted, the car was purchased and has remained in Oregon.

I am assuming there are rubber lines here in the engine compartment attached to metal, and then another rubber line into the tank?
