As seen in this picture but all metal if possible. This one is on my car now and is leaking. Of course its the pressure side of the pump. You can see the air in the line. I looked around on howertonengineering didn't see it. I suppose I could look through SMCs catalog and find it.

Not sure where you found those push-on fittings. You can get the 90-degree fitting here (http://www.aquamist-direct.com/1-8-bsp-swivelable-compression-fitting-qty-discount/).

The AEM fitting is extremely restrictive, not good for the suction side of the pump.

This was an HFS-1 to HFS-3 upgrade. The original HFS-1 kit included those swivels to connect to the pump. See http://www.rallysportdirect.com/catalog_photos/products/aquamist/aqu_806_081rd_1_lg.jpg

so that swivel is 1/8 BSP on both sides? I would need a pump inlet adapter as well ? http://www.aquamist-direct.com/806-558-6mm-pump-inlet-outlet-adaptor/

AEM fitting? You referring to my filter? Sad to say that the Aquamist filter isn't very good and over time it leaks. I have a metal tank that I don't want to drill to install your intake filter. Always a hassle trying to get it to seal. I wish Aquamist would make a filter like AEM has. PnP no nonsense.

I never know they offer an H1-H3 upgrade.

I have not heard once anyone reporting a leak on the in-tank filter. If the hole is not perfectly smooth, it will leak but it is not our fault.

Yes, you do need two 3/8 BSP to 1/8 BSP female and two 90-deg. fitting.

All push-on fittings will leak in time. This applies to the AEM filter if they supply push-on fittings on their filter.

Have you tried this one (http://www.aquamist-direct.com/806-257-inline-100um-stainless-mesh-filter/)? It is a compression type fitting.

They don't offer an HFS1 to HFS3 upgrade I just called it that. I made the move from an HFS-1 to an HFS-3. I hope that clears it up.

I'll also need two 6mm to 1/8 BSP compression fittings as well ?

That aquamist filter you referenced is the one I dot have much luck with. The internal plastic Orings crack and it leaks. Already tried a few and gave up.

Plastic will crack from over tightening. As far as I know, the AEM filter is designed for 1/4" hose (6.34mm). How did you manage to splice them with 6mm hose?

The internal o-ring is made of nylon, Majority of fishing lines are made with nylon. I cannot see how it can crack. Have tried to break them with you hands? They win every time.

So you can continue to use the AEM filter with 1/4" push-on fittings. The aquamist 90-degree fitting+1/8BSP/6mm compression fitting might work. May need to drill the collar entry hole to 1/4" to accept the imperial hose.

By no means this is a recommendation from me so if it doesn't work. Don't blame me.

What kind of restriction are you referring to? Please explain.

I must have gorilla hands then because they leak. I did have one that lasted for a few years then started to drip. I am using 6mm hose with the 1/4" push on fittings. I know its not a perfect fit and tested it for leaks, so far so good. If it starts to leak I can unscrew the 1/4 push on fittings and screw in some metric ones. No drilling for me sir, I try to avoid at all costs modifying things!

As for the restriction question I edited that from my post because I was reading that the pump uses a 1/8 BSP to 6mm hose adapter anyways. Dumb question sorry.

Gorilla hands or not, a 6 mm line will not fit into a 1/4" push fitting without the risk of leaking in the future.

If you are not prepare to use all aquamist supplied fitting with the kit, I cannot see how I can help you. It is not that difficult to drill a hole on sheet metal.

I rather you not making remarks on our components without mentioning there are many size-mis-matches on your set up with third party imperial fittings.

"All" push-fit fittings will leak, depending on when. The AEM filter uses push-fit fittings. I will repeat, the AEM filter is a very restrictive, not recommended for the suction side of the pump.

There are mismatched sizes. Thanks for your help Richard.

Hi Richard reporting in. New swivel fittings are in they are a very nice piece! I am running a dual nozzle setup, .9 and a 1.0 not seeing any flow problems from the pump with that AEM filter installed. Has Aquamist done performance tests on the filter itself ?

Post a picture please.

The AEM filter is 40um, it is naturally n-more restrictive than a 100um. We have to ditch the filter on a 4x1mm set up.

Due to the mesh size, it can clog up much sooner. Why use a 40 micron filter when the smallest nozzle orifice is over 300 microns,

What would you like me to take a picture of ?

BTW unrelated to this post, I see this problem with my gauge http://www.aquamist.co.uk/vbulletin/showthread.php?t=2730
I do have mine in an air vent. Im going to try and adjust the FSDL like you've mentioned. This problem for me started day 1 out of the box before I even drove it. I thought perhaps the black cable going to the gauge was bad so I tried my spare with the same result. Everything works perfectly fine however.

FYI did some searching around. I was reading around I saw that someone mentioned the AEM filter uses a paper cartridge. That isn't true, or at least for their latest filter. I have a stainless mesh in mine.

Also, found this filter designed for alcohol. Very little pressure drop .15 psi according to aeromotive. Looks like a gem, could screw on some Aquamist pump bushings and have a real professional setup. http://www.summitracing.com/parts/aei-12316/overview/

It looks nice enough. Make sure it has cone shape filter element inside rather a flat disc. Disc takes on time to clog.

I have seen a great deal of people using AN fittings, they are all made of aluminium, all prone to corrosion in water or methanol. We always use nickel over brass. We use to offer a checkvalve in ali housing, over time strange white power appeared and clogged up the jet.

I did and that looks neat! I was going to buy it, my FAV is in a tight area in the firewall. I went with the trunk setup because its easy to get to and service. Also the reason I'm hell bent on a trunk filter is the fuel cell Im using has foam inside of it for sloshing. It can come lose and I don't want it inside the pump/lines/FAV etc.

Thanks for the picture.

You need to remove the sticker on the allen key slot so you can tighten the fitting properly. Never over tighten or the seal collar will crack. Use a 5mm allen key.

If it is working, leave it. I still concern with leak about those push lock fittings long term. We shall see.

Thanks I saw the warning about over-tightning so I left it alone to see if it would leak. None so far so not going to make it tighter :). I'm going to replace the filter with an aeromotive and buy the pump fittings to adapt it. I'll monitor for corrosion like you mentioned
