Nice compact gascolator, good quality of construction. The only reason I did not give it 5 stars is it would be better if it had a way to safety wire the bowl locking ring.

Very high quality fit and finish. I would have given 5 stars but the design provides no positive provisions for mounting it. Other than suspending it from the fittings (generally a poor way to go) theres no threaded bosses or tabs to attach a good mount to.

Q: Are there any mounting provisions for the ACS high pressure gascolator?

Per the manufacturer, the high pressure unit (part # 05-04248) does not use the same bracket as the regular unit. It uses the Gascolator Mounting Flange found in the "Accessories" tab (part # 05-00907).

Q: While Gascolator (Part # 05-04248) specifies that it is high pressure, does it still work properly in a low pressure situation? I would like to use it downstream of a Facet pump (part # 40108) that will be used for boost/prime/backup to a mechanical pump. The configuration will be: Tank- Inline Filter-Shut-off Valve-Facet Pump-Gascolator-Engine driven pump. This is a carbureted engine.

Yes, it works in low and high pressure applications.

Q: Is the ACS High Pressure Pressure Gascolator a FAA approved for use in certified aircraft?

No, this gascolator is not FAA Approved. It is intended for use in experimental aircraft only.

Q: What are the fitting sizes? What is the maximum fuel flow?

Per the supplier: Top has 1/4" pipe ports for 3/8" fuel line and one 1/8" pipe port for primer fitting.It is tested to 50 PSI, but we do not have a fuel flow rate.

Q: I have your classic mounted on my plane. Does the ACS HP gascolator top have the same dimensions as the classic? If so, then I can easily replace my old one for this newer style. I hate the bailing wire style.

Yes, they both share the same dimensions.

Q: Can the ACS high pressure gascolator be installed with AN840-6D fitting?

Yes, this will work as this will have 1/4" NPT ports and AN840-6D has a 1/4" NPT thread.

Q: What is the weight of the ACS high pressure gasoclator (plus firewall fitting)?

Approx 0.36 lbs.

Q: Is there a filter screen in the bowl or the exit port?

There is a screen at the top of the bowl.

Q: Does this unit support the fuel throughput required by fuel injected engines?

It is tested for 50lbs but we do not have flow rate specs for this unit.

Q: What micron size screen comes standard?

This comes with the 120 micron screen.
