Poll ; how many mechanical fuel pressure gauge users actually had a leak in the cab

[The patriot]

Oh yea....

I've got snubbers on both senders.

I have had a mech gauge for a year now. No leaks.



My isolator crapped out and would cause crazy gauge readings (28psi and up!). I talked to Rod @Wildcat about it and he said that his experience was that almost ALL isolators fail eventually.



I took out the isolator and run it direct. No leaks. No noise. No problems.



FYI-- I get my readings straight off the VP, and have no noise issues. The Gauge is a Hewitt from Enterprise engine. Great gauge and highly recommended.



BTW-- I discourage the isolators in general, especially those that use glycol. The glycol ate through my isolator and eventually my VP swallowed the mixture

Hohn, this is exactly the kind of input I was wanting to hear, along with the other responses I received on this thread. I want to thank all you guys .

Anyway, I do not know what the factory gauges look like in a 2002. Are they the same as a 2004? I want to look at the Hewitt gauges, if I can find pictures of them somewhere on the Internet. If they match fairly close to the factory gauges, I would consider them. Is Enterprise one of the venders on the TDR? I will look while waiting for a response... ... ... ... ... ... .

Thanks again everyone!!!!

You can try www.enterpriseengine.com and talk to Loretta. They have they Hewitt gauges. I bought my kit from them, and it was the included isolator that failed. I had problems with leakage and stuff trying to use their hardware, so I ended up scrapping their stuff and using braided stainless to the gauge. I have grease gun hose from the VP (via adapter) to an adapter than connects to the braided which runs to the gauge.



The Hewitt gauge from Enterprise has a greenish lighting that matches the stock gauges on 2nd gens. The lighting is though-the-face, not the crappy halo lighting like my Autometers use. It's nice. i have also heard good things about the di-pricol gauges and the ISSPROs. i wish i would have gone with the ISSPROs over my autometers for boost and pyro, but im real happy with my Hewitt FP gauge.



FYI-- i suspect that one of the reasons i get not hammering is because I have a Fitch Fuel catalyst plumbed into the fuel feed line after the LP. This canister (about 3/4 the size of a coffee can) may act as a buffer that prevents the hammer.



All i know is that my gauge is dead quiet-- but i can't say exactly why.

I've used a mechanical fuel pressure gauge w/isolation valve for over 25K miles (9 months) and haven't experienced a drip... not a one. Connected steel braided fuel line to bottom of fuel filter housing via needle valve (isolation valve) and ran it to A-pillar inside cab... no noise either.

Once - when I put my gauge in and didn't tighten it down all the way it should have been - since then... NONE - of course it's about 3 months since then.

I'm hooking up a DiPro FP gauge to my 03. I have ordered a tapped banjo from Geno's. Can someone tell me what size fitting will mate up with the tapped banjo?



TIA!

On my '99 I bought a Stewart Warner gauge with all the fittings and boost type fuel line and ran it up to my A pillar. 3 years and 50,000 miles with no problem. No isolator, snubber, no nothing. Not a bit of noise or needle fluctuations. I did tap in at the 1/4" fitting on top of the filter. Maybe that's why I don't have any of the symptoms you fellas are having. Best $35 i've spent. It has let me know about two dying lift pumps possibly saving my VP44. See ya, Jason

Mechanical Guages on three trucks that I've done (one is my own two others are friends) All have the isolator and none have ever had a problem.



This after having problems with sending units on two different electric units.

Been in a year . liquid filled with no snubber . Nice and quiet but ugly
