You need a #18 adapter. Make sure the cups you order are HO style. I believe the "most confused"[big grin] one has a post with all the variations in this section of the forum.

Here is a link to what you will need for the T70 bottom feed gun.

PPS for T70

I believe you can order from these guys. Or just call them and they will guide you. Fuji Spray also recommends dealing with them.
Cheers,

sorry，but it look s like it is still bottom feed when using adapter. I am trying to understand pps system's benefits.

You can't convert your bottom feed to top feed ( gravity). You will have to purchase another gun. The T75 gun. The needles and cap set for the T70 is compatible with the T75. If you go with the M series or GXPC gun you would need to purchase additional needles and caps as they are not the same as the T series.

Yes, it will still be a bottom feed, but you can flip the gun over, spraying with the cup and hose pointing up (the gun will now spray in any position, (this is true if you're connected to a separate pressure pot also). You cannot do this with a conventional cup on the gun.

The PPS system uses a flexible material liner so when start off, you bleed the air in the liner above the material.  That being, it allows spraying at any angle as there is no air pocket to deal with.  If you ask me, if the cup is above or below the gun, either way it'll be issue in some situation.

If you want the best "all angle" setup, you'll have to go with a pressure pot system.

3M PPS HO Style
 
Thank you all. So PPS can let you spray more difficult angles and provide easier cleaning. Does it provide better finish result? I am debating whether I should spend $200.

I found amazon has cheaper price and wonder whether I missed anything. Below is all I need for PPS system, right?

3M 16054 PPS Adapter 18 $28.05

3M 16124 PPS Type H/O Large Pressure Cup $66.75

3M 16024 PPS Large Kit with 200 Micron Filters $62.70

Thank you!

Finish quality is ultimately in the hands of the person holding the gun.

Did you contact Fuji about the T-70?

Tom
 
I contacted fuji and sent my gun to their contractor to fix. Haven't heard back from them yet.
 
I got the gun back today. They changed a nozzle and screwed the new nozzle super super tight. No leaks anymore yeah! But should I do the same? I just don't want to damage the gun.
