Snubber with Electric Fuel Pressure Gauge?

[MartyK]

I’m in the process of getting some gauges for my truck. I want to use the Autometer Phantom II fuel pressure gauge; it’s a 0-100 electric gauge. My question is. Do you use a snubber and / or a needle valve with an electric gauge? Or this that just for mechanical fuel pressure gauges.



Thanks

I am using the dpricol 0-30psi mechanical guage. With your 05 you should only show 9-10 psi. Will it be hard to read on the 100psi guage?? I would not think that the guage would move much to show 10psi. Not for sure though. I am tapped into the bottom of the filter base and am using an isolator. It works great. Can't help you with the electric one.

I'm a big believer in using a snubber for an electric gauge, but there are some who say that it isn't necessary for the CP3. I feel it is cheap insurance.

I replaced the stock banjo bolt on the bottom side of the fuel filter canister with a tapped banjo. Then, I installed a snubber to dampen any pressure spikes. Attached to this I have a 30-inch rubber hose with 1/8NPT male/female ports to eliminate physical vibrations from the engine. The end of this hose runs up to my brake master cylinder area where I fabricated a bracket to hold the sender end. On this end of the hose I installed a street-T and mounted the sender on one outlet. The other outlet I plugged with a hex plug which I use to bleed air out of the line after doing a filter change.

Here is the snubber I bought, which works great (PS-8E).....

I also used a 30" hose from Geno's Garage... ...

MartyK,



Drop the Auto Meter down to 0-30PSI (part # 5760), we don't have any issues on the electric FP guages needing snubbers. In fact in most all cases if you use an isolator on a mechanical gauge you don't usually need one either. Get a Banjo bolt and the Auto Meter Sender will thread right in for you. If you're confused let us know.

Thanks for the replies.



Mark, is the 5760 gauge part of the Phantom II series? I would prefer a 0-30psi gauge.
