Electric fuel pressure gauge - best way to protect sender?

[CumminsPower98]

I have an electric fuel pressure gauge (Auto Meter 4363) installed but think I may have killed the sender because I mounted it without a gauge snubber (gauge not working). What I want to know is who out there is running electric fuel pressure gauges and how are you protecting the sending unit. Is there a better way to protect the sender than a gauge snubber? I have the sending unit mounted in the head of the banjo bolt, which supplies the injection pump after the filter. Any ideas would be greatly appreciated! Thanks,

Mark

You might have killed the sender by mounting it direct to the banjo bolt- it can't take the engine vibrations shaking it up.

Try a remote mounting with 1/4" fuel hose to isolate the vibrations.

I've got both of my senders mounted to the fuel filter housing, using brass 90's. So far so good.

You can order a short length of -4 AN hose and attach the sender to one end, and the other end to the fuel pressure source. This will help to eliminate most of the vibration.

EMDDIESEL has the best solution. Not only does the hose eliminate the vibrations from the engine, but it will act as a snubber taking out the sharp "pulses" found at the input of the injection pump. These constant pulses kill the transducer.

The way I did it was to install a snubber on the banjo bolt then use a grease gun hose to mount the sender to the fender wall, grease gun hoses are 1/8" NPT on both ends, will take 10,000 psi and resist diesel, cost less than $5. Only problem was my senders still bit it, after the second one I installed a mechanical gauge, cheaper for the whole set up than a sender. This is for a 12 valve, the lift pumps on these pulsate much more than a 24 valve electric pump.
