To the left of those gauges is the sender for my in cab gauge. I tinker with the fittings an lines a lot for the systems I sell so I like having the gauges under hood as well.

 

The two gauges I have now don't bounce around and the one I had before did not either. I use small resrictors I made and I loop the rubber lines around to kind of buffer the pulses and my fuel line is all rubber from front of tank to the VP.

 

I re-installed the fuel pressure gauge system using a pressure snubber at the VP 44 and a rubber line to a needle valve, from there it's plastic tubing to the gauge. No more leaks and no rattling gauge but the pressure snubber really takes away from the "responsiveness" of the pressure gauge readings. To better relate, it's like the gauge is filled with molasses now. It works, it doesn't rattle, and it doesn't leak so I'm now happy.

 

It would be nice if you could share that part number and maybe help someone else out.

 

If your looking for the snubber go to McMaster Carr and do a search and you'll find it.

 

They have several different orifice sizes available at Mcmaster-Carr if I remember right. Which would you guys suggest to people?

 

my issopro fuel pressure guage is leaking around the thread to the guage, what can I use to stop it?? i know i can't use teflon tape but is there a tape I could use so its not eat'n up by the diesel fuel ?? thx

 

Permatex Number 2 or liquid teflon paste (Loctite) PST. In both cases make sure you clean the threads well (electronic parts cleaner will work)

 

thanx Mr.E ...i mean Dr.E

 

You can use teflon tape, but it has to be the "yellow" fuel rated tape.

 

You can but if you ever got even the smallest chunk of teflon in yoiur injector pump...when I would think it would be a big expense

 

Sure you can and it will be fine until you have to take something apart and can't get the tape debris out of female fittings without taking everything apart.
Teflon tape is for plumbing, not for vehicles, I don't recall ever seeing tape come stock on any vehical, think maybe there is a reason for this?
Use Permatex #2 or anti-seize for thread seal, easier to find than yellow tape anyway.

 

Thanks for the automotive/plumbing lesson. I've used the yellow tape without issue. As we all know, whatever comes stock on a vehicle must be the best solution.... Use what makes you feel comfortable!

 

Mike, I fully understand where you are coming from but when you consider one of the most important factors in vehicle design is to make sure it doesn't come in for warranty issues you can understand why manufacturers are picky about which materials they use.

 

As has been mentioned, the Loctite hydraulic thread sealer works well and is not too expensive as a tube lasts forever. Be sure to get the thread cleaner also from Loctite.
