Im going to be shopping for a fuel pressure setup and noticed autometer makes a fuel pressure gauge with an electric sender. This seems like the best way to keep fuel out of the cabin space for safety. Thing is, seems like everyone here likes to use the mechanical setup...why? It looks like the setup is a little pricey, but it would be worth it to keep a pressurized fuel line out of the cab, and the simplicity of hookup...

 

Everyone has their own preference. I just got the electronic autometer gauge and it seems to work great to me.

 

The electric is 13 times more expensive than the gauge I have in my truck.

 

i was told the mechanical is more accurate

 

There has been quite a few failures from one of Autometer's electric fuel pressure gauges. I'd stay away. I use Westach's 30psi electric fuel pressure gauge. From Geno's ~$70 iirc.

 

I saw that one and marked it did you use a snubber/ restrictor for the sending unit to help reduce the pulsations. Thanks Ed

 

I've been running a Westach electric gauge I got used for almost a year, and save a problem with some electrical connections in the truck, it has been just fine. I dont have a snubber for the sender, but now that you mention it, it isnt a bad idea.

My thoughts are to run a line of choice(-4AN) from the source of pressure to the fire wall then mount the sender at the fire wall, the adjustable snubber/restrictor can either be at the fire wall or the source of pressure. putting the snubber at he fuel pr. source gives you the opportunity to shut off the entire line if there is a problem and also lets the line to the sender help in absorbing some additional pressure spikes and vibration. That is the plan so far need to order parts. Ed

 

I have yet to find this "snubber", where can I find one, what does it look like?

 

It looks like a little pipe fitting. McMaster-Carr has them, just type "snubber" in the search box on their site. You want the sintered style. Don't get the one rated for water and light oil, it will allow too much pulsing. Get the one for gases.

 

I don't mean to hijack but I've just temporarily installed an ISSPRO R5604 fuel pressure gauge with a 6' AN4 stainless braided line coming off the fuel pressure regulator. As such, I'm not seeing any pulsations at the gauge.

Anybody else running the same gauge with similar results?

I'm trying to decide if I need a snubber with things as they currently are.

 

I know theres no pic - http://www.vulcanperformance.com/ser...Snubber/Detail

But its what you need.

 

I think your regulator is damping out the pulsations. If it's not bouncing you don't need a snubber. I would put a shutoff valve down at the regulator in case you spring a leak, even with the braided hose.

 

For my 98 24v I read am not sure where that they had some serious pulses of high pressure that are not noticeable on the gauge but can cause the gauge to malfunction and it was if I recall 98.5 and 99's. Ed
