Looking or Fuel Pressure gauge advise

[speedtuner]

I have problem keeping fuel pressure gauges working under my hood.
I have a fairly standard DIY check valve conversion. Oil feeds in the front of the heads & purges out the rear. My junction manifold sits in engine valley. Works awsome, has for 80K miles. BUT, I can't keep fuel pressure gauges in the thing. I keeps pegging them out. I do have the the stock cv's(or whatever they are) that were on the heads removed.
I have heard that while starting the truck there can be spikes. I'm sure this is what is happening. I had heard this is because of the split shot injectors. I just switched to stage 1 single shots, I thought my troubles were over. Not so, I just pegged another gauge.
What to do?

What type of pump do you use for VO? Do you have one for VO and one for diesel or?

[speedtuner]

yes, stock pump for D2 - Fass hpfp for VO

its not adjustable? If it isnt then you need fuel regulator on that bish ASAP. I know some of the older FASS didnt come with the regulators.

I have an isspro ev2 FP gauge and it works well. My sender is down on the frame rail tho.

yes the vo pump is adjustable, that has nothing to do with it though, it's doing it while starting up on d2

7.3 or 6.0? 7.3's are notorious for large spikes. I've seen check valves actually blow apart from this. There needs to be some length of rubber line to absorb this, not familiar with your setup at all though.

Its a 7.3L. I haven't had any other problems with the spikes other than the gauge. I just ordered a dampener from summit racing made by Autometer. The dampener was apparently made for Cummins engines which according to Autometer have even worse of a problem(they say pressure spike up to 1000). We'll see how it works.

What PSI guage are you running?? If its a 100, switch to a liquid filled 200psi unit. Should take care of it.

Could you provide a link to it?
