Fuel Filter Manager - Different Cover???

I'm exploring the source of a fuel leak on my '99. Appears to be from the cover of the fuel filter manager. However this cover is completely different from the one on the '95. The '95 has a plastic ring that screws down over the filter which has the cover built onto it and it's metal. Also, on the '95 the filter only fits one way into the notches of the fuel filter manager. The cover on the '99 is solid plastic and the filter is separate from the cover. Though there are the same notches in the fuel filter manager, this cover and filter do not lock in to them. Futhermore, the O-ring sits in the top of the cover and it escapes me how it seals over the notches in the fuel filter manager:

Is this a case of older is better? Should I just buy the threaded plastic ring hold down and use the old style filter?
 
Thats the type that Heath and SSDS sell now. I heard bad things about them before, with the leaking.

I dont know if there are good or not, but not personally had any problems with the regular filters.

And just as I had suspected before, these leaks always seem to appear at the filter manger. If you go back to regular filter youll have to get a plastic nut too.

Could not replicate the leak today. The plastic nut for the old style filter is
$13 at the stealer, but have to order it.
 
Where there is a leak, there is possibility of an air leak, so best to get it solved before funny things like OS and CPS and fuel circuit codes show up unexpectedly.
 
thats the new design for the fuel filters i think. put a new fuel filter in when i changed injectors and that is what came in the box. the fuel filter i put on before that was the old one so i think there phasing thoses out
 
I thought plastic caps filters were non Stanadyne made filters ie Balwin or someone else. Stanadyne somehow trade protected thier filter so all the metal topped OE looking filters are made by Stanadyne or licensed by Stanadyne or something like that (no matter whose box they are in). The cost of filters has risen and now there is more competition.

Make sure the little metal ring seal support did not get left behind by the last metal topped Stanadyne filter and is now stuck up in the plastic cap. The little metal band is pretty thin and can be overlooked.
 
And FYI I have had little errors putting in a new Stanadyne filter and disturbed the seal then the pinch or what ever caused a leak. Not sure how delicate the plastic tops are but might want to look at seal closely. Might just have to look at a new one and look for differences pinch marks etc and install the new one to see if it was just an error in installation. I usually have 2 on hand in case I mess install up then shelf extra for next time if I don't flub.
 
They don't have to be lined up with the notch anymore. It takes about 1/8 turn to tight with a filter wrench. I have had it for about 6 months now, no leak but without that 1/8 turn, it will leak. It is actually more forgiving than the old retainer ring in terms of pinching the gasket.

The bleed valve needs to be a little tighter also. I just used a plier to tighten it a little.
 
I have a small hand and not very tall, so I cannot just lean over. That is my experience but no leak and car is running. So I will keep it in there. Besides that is the direction the filter is going. Something about reducing the metal for the environment.

I actually have been having trouble with the original style not tightening properly, may be after 15 years that plastic retainer started to melt slowly in TX summer? This one, at least, I don't have to locate a new plastic retainer.
 
There are a few brands, I used the Baldwin ones. I am not sure if the Fram is rebadged Baldwin but I know there is also Wix. May be others.
 
As said, this is the new style in 1st post. There is an older model that requires the black retaining ring. Wix have 2 model also. As a matter of fact, right now, all brands have both old and new model. It is designated by different part no.
 
Hmmm.. I must have run Arizona out of filters. Now I get a filter like this. (After all of the old one I have gone through...) Must say it is easy to install vs. the old line it up one.

Any word if the old style is still being made?
 
I've been using the Baldwin with plastic cap for quite a while now, it has more surface area (more pleats) than the older ones I used to use. I find the new caps much easier and cleaner to use. I've had 2 leakers - one was missing the o-ring so I had to rob the ring from the old filter and put it in, the 2nd I have no idea what was up, it screwed on fine but leaked like a sieve, removed and re-installed (same filter) twice and the leak was gone.

I'd suggest you pull the o-ring and re-seat it to see if that's the problem.
