What is this??

[Dave WM]

this is what is coming

• Are offered as a universal in-line fuel filter element. 
• This high flow inline pre-filter element is an inline fuel strainer for pre-pump installation.
• Are available in either 3/8" or 1/2" I.D. sizes for in-line fuel line installation.
• Both of these in line pre-filters from Fleetguard have a 24-micron stainless mesh inner cage.
• Can hold a 13-gram capacity which prevents large particles from entering the fuel pump.
• The Fleetguard replacement inline fuel filters are designed for inlet side filtration only!
• Fleetguard In-line Fuel Strainers are a high flow element that will not restrict fuel supply to your fuel pump.

its pretty big, 2" by 4" if I read the specs right.

Physical Dimensions of the FASS 3/8" In-Line Fuel Strainer

• Largest element OD - 48.489 mm (1.909 in)
• Overall Height: - 98.81 mm (3.89 in)
• Inlet Connection - 0.375"
• Outlet Connection - 0.375"

I will use this for a while (I hate buying stuff and then not using) and report back on any weird pump noises if noted esp when summer time kicks in. Guess it has to be better than the G3 that is in there now?

The Aeromotive link ( Tech article 101 ) that I provided  explains things very, very well  Fuel Lab and other HP Fuel supply companies all follow the same criteria. 

24 Microns sounds way too small regardless of the advertising blurb. Especially if you are running a High performance Fuel pump with a lot of volume. Problem with that small of a filtering capacity,  is that fine particles can plug up the Medium very quickly. 

Aeromotive and other high performance pump Manufacturers recommend a 100 Micron large capacity, non restrictive  pre-filter ( or sock/strainer on Intank pumps ) and a 10 Micron large capacity filter post pump but before the injectors. 

Edit: Dave can you provide a direct link to the Fleetguard product. Hopefully with pictures and full specs. And what F/Pump are you using. Engine specs?

CM, are people you offer tuning advice to "customers"?  Sounds like you have a business but I think that you're just offering free support to people over the internet.  Is there a business behind it?

Just verifying.  It's my nature.

This comes across as a slightly  weird and rather insulting Question ZH. Not really any of your business. 

But I have nothing to hide and it's no secret:  Advice is free. Tuning sessions are not.  I've tuned several members cars on both Hybrid Z and Classic. And it's been mentioned enough times by Customers  to seek me out and pay the very reasonable fee's for my services, that I find it hard to believe that you would not have noticed. Hence why I find this question slightly insulting. 

I offer Paid Remote Tuning sessions will full unlimited support to my Customers. And I have a steadily growing list of satisfied ( Paid ) clients.  Just did three Remote Tuning sessions over the Easter weekend. One in Arizona, one in Chicago and one in New Zealand.

I try treat these people in a Professional manner and as if they are personal friends. I  offer Guarantees on services provided ( You aren't satisfied... you don't pay me. Simple ) , unlimited support after initial Tuning session, often for months after the original tuning session and also spend countless hours sorting issues out engine and hardware, wiring issues with the installs . I keep Logs of all E-mail messages, engine specs , Data Logs , Tune modifications on each individual "Customer ". 

Is it a Business?  Well I never said that. If it was, it would be a very poor Business model as my Time invested with each Tune in no way equates to my Fee's charged. To me it's just an interesting Hobby.  Something I'm good at and people recognise that.  I can help out the Community while putting away a few extra dollars to pay for parts on my Z.  I should make it a Business as I could get some big Tax write offs.... but that' a PITA for Paperwork.... and I'm just not that smart. 

Hope that satisfies your " Verification process "....

Madkaw had an issue with one I think. I've run them on everything from low psi Mercury outboards to 36 Psi on my 280 before the fpr to check for pink colored fuel on my '77. No leaks. I have them on everything but my Camry and Exmark mower without issue since the late '80s. Just change the screens. I've been lucky I guess?

I ran this glass filter for at least a year at what, 36psi before the FPR?

Its cheap so I am not out a lot if its not the correct thing to use.

Why not run something industrial?   The farming industry dumps non-performing products pretty quickly.  The aftermarket auto industry focuses on flash and buzz.

Probably spend more on the fittings than the actual filter though.  1" NPT.

Fuel pressure damper. Leave it in place.  Helps absorb " Water Hammer " from the injectors when they open and close. Like in an old hose when you shut a water tap off too quick and the pipes go Bang. Same principle.

I thought it was for smoothing pump output variations as the fuel system is open with a return line as opposed to plumbing to the bathroom which is closed. I did not think a water hammer effect would occur in an open system?

[Chickenman]

Yes, you will get a Water hammer effect in return style EFI system. Particularly bad if you use a Multi Port Mode or  Batch Fire Mode with Simultaneous injection and a single squirt that opens all injectors at the same time. Gets really bad with larger injectors. You can often see the pressure pulsing on the FPR gauge if you have large injectors and choose Batch Fire Simultaneous injection 1 squirt. Then change it to Alternating 2 squirts. Same amount of fuel injected per cycle ( 720 degrees ) but pulsations in fuel rail much less with 2 squirts alternating.

 A liquid filled FP gauge can mask this effect. And unless the have a bleeder compensation valve ( $$$ ) the Base reading will vary with engine bay temps.  A good undamped ( non-liquid gauge ) is all that is really needed.  

A lot of the  premium high performance EFI regulators are designed so that they operate as both a regulator and a damper. From what I've read on the Aeromotive and Fuel Tech sites.

Not enough screen capacity and too small of filter media. It will cause a restriction at the pump inlet. Especially on high volume pumps. Personally, I recommend the Holley unit a lot. It has a decent size filter area, 100 microns and the 3/8" NPT fittings are nice. If you have AN fittings I really like the Aeromotive and Fuel Lab units.

Those aren't really designed for EFI pressure. They are usually meant for lower pressure Carbureted motors.  And they have a very small filtering area. Compare it to just a stock Nissan EFI Fuel filter in the engine bay. You would be much better off just using the Nissan Fuel filter..... IMHO 

I can't quite see if you have the stock Nissan fuel filter in place on the passenger side firewall. It looks like you may. If so, there is no reason for this additional glass filter. 

The other bad thing about glass fuel filters  is they can  shatter in an accident. Lovely way to start a fire . Really bad deal if you are knocked unconcious......
