I need to know where i can get a fuel pressure isolato made for diesel fuel. Does anyone know where i can get one or if like jegs or any other company makes one. i know summit doesnt sell one because i have already checked with them and they dont have one for diesel fuel. any info would be helpful, thanks Eric

 

You need to fill in your sig so we'll know what you're driving.

Are you asking about an electrical isolator, or a needle valve for a mechanical gage?

 

Most guys here will tell you to buy this...



It will cost you about $20 bucks for all of this... And it works better than a isolator...

Just my 2 cents...

 

I have one that came with my kit that I installed last week. I chose not to run it, but am wondering if I should have?

 

I got mine here: Fuel Pressure Isolator. I read the posts about just using the needle valve but I figured that the peace of mind knowing that I'm never going to have diesel leaking into the driver's compartment is worth few extra bucks. I'm not criticizing those who run without the isolator - I just didn't want to go that route.

I didn't opt for stainless braided hose, though. I got some fuel-rated tubing and barbed fittings with clamps that are rated way higher than the expected pressure range. The pressure will generally be below 30psi so if you get something rated for 100psi or more you should have plenty of safety margin. Check your yellow pages for a local outfit that sells hose and fittings or makes custom hoses. I got 3 feet of hose, two barbed fittings and two right angle swivel 1/8" NPT fittings for about $10.

call piers diesel they will have one

 

I got one with my Diprocol FP gauge from genos, as soon as its approved I got a pic of how I mounted mine.

 

how do you fill in your sig or your information so you know what i have

 

Click on the "user cp" button up towards the top of the page.

Once there, "edit profile" then fill in the signature box.

Isolators are a waste of time and money on diesel engine. Most diaphragms fail within the first 10,000 miles and the owner will be none the wiser that diesel fuel is making it to their gauge. You may as well just install a coupling for all an isolator does.

 

Hey Guys,

I just read through this thread, and would like to install a FP gauge in my recently purchased truck. Can anyone direct me to a kit, that would sell everything I need? Also, I'm pretty mechanically inclined, is this a do it yourself job? How long should it take, and any special tools required?

I have found these on ebay:

Are these kits all inclusive,....everything I need to get the job done. I'm thinking I'll probably just plumb straight into the cab, no isolator.


Any insight, or direction in this matter would be appreciated.

 

Silver, the prices seem too high when you consider this is probably the same same gauge that comes with the kits http://www.surpluscenter.com/item.as...atname=engines

Putting together the rest of the system will probably cost you less than $20

 

Hmmm, interesting. Thanks for the link infidel.

I'm not 100% sure of what I need to get this job done, and like the idea of a kit, with instructions......so I may just pony up for the kit.

 

01DodgeDiesel,

We have the isolator you're after it has a membrance designed for deisel, gas, etc except methanol's It's pretty reasonable at Edit and is easily installed, we even have a tubing kit from the isolator to the gauge for Edit with all the fittings etc. Been using them for 4 years and never replaced one yet! Even use on on my race car!

Now here is some other info most folks don't know about, not trying to slam anyone just placing info here for members to use at their discretion etc.

NONE I repeat NONE of the gauge manufacturers will honor their gauge warranty if they smell any kind of fuel in their fuel pressure gauges. How do I know this you ask, well it cost me 6 fuel pressue gauges when I sent them in under warrannty, that's how!! If an isolator is installed correctly and it's a quality unit it will last and give very accurate readings, our race car has to be at 3.5 PSI, not 3.3 or 3.7 , but 3.5 period and the system is working perfectly. Now this also keeps fuel out of the interior, if it ever leaks you will never get the diesel smell out of the interior etc.
