DiPricol gauge
 

I need some help installing a fuel gauge I just got one and I am installing it on the pillar of my 2000 dodge ram 2500 4X4 5 spd . When I order it they also sold me on a isolator, banjo bolt, and it also came with some other hoses.Thank you guys!

what,no instructions?:humm:

No instructions were they supposed to send some?

Hmmm... Odd...

Here is how I hooked up mine... Its just basic but it should help...

So where do I connect the air dog hoes?

(D'Oh!) My bad...

I kept my stock filter and use a Vulcan Big Line kit previous so I have the line between the VP44 and the Stock filter setup already with Push-Loc Tee and place to tap the fuel line. So the new ones have the tap in the elbows. Now the electric sensor is my low pressure switch.

Ok so finally I finished putting the gauge thank you Mopar1973Man for all the tipshttps://www.dieselbombers.com/member...6-img-0003.jpg take a look at the the that I made up tell me what you think.https://www.dieselbombers.com/member...8-img-0005.jpg

Let me know what you think of the tee connection .

I just test drove the truck and the gauge its reading 13 psi its that normal also when ever the truck is on a stop the psi seems to go up to 14 psi .I have also installed a new vp44 injection pump from blue chip.

Yeah sounds about right for stock fuel system... Now look at WOT (at highway speed) and Idle pressure...

Normal Range is 10 PSI to 20 PSI... Anything under 10 PSI is asking for VP44 pump damage...

I dont have a stock fuel system I got the air dog 100

O one more thing I filled up the gauge part with liquid silicone but it did spilled a little there were air bubbles on the hoes will that affect the pressure reading?

Oh... Isolator... Yuck... Yes... Those air bubble do effect the gauge operation.

So yeah the pressure reading is most likely lower from the air bubbles...

Typically AirDog is up around 15-18 PSI...

A little air in the gauge line will not have any effect on normal operation. Also, pressures will read exactly the same either way.

The reason why we use glycol or silicon is to use a non compressible liquid in the line. Actually, they will compress, but far less than air. The reason this is done is do that the throw of the isolator is lessened to obtain the same pressure reading. In other words, the isolator diaphragm has to move further if only air is in the line. So, if you are at or near the travel limit of the diaphragm, you may get incorrect readings. However,when air is compressed or a liquid is compressed the end reading will be exactly the same.

Remember to always reset an isolator upon an install. Just pull the fitting on the gauge side and gently push it back to the engine side with a blunt object. I like to use a pencil eraser. This gives you full travel.

Isolators bah.:booo:

I agree with ya... But some people still try...:w2:

isolators to me serve to save the gauge more than anything else.

We get calls every day about how a customer has a gauge rattle. They want it warrantied, but removed the isolator. The isolator serves as a shock absorber for the system. Since most people do not understand how a snubber is supposed to function and or cannot build one of their own, an isolator fits the bill for 99% of the public.

A lot of guys don't trust isolators and that's fine. But when working correctly, they do serve a great purpose in the fuel system.

In fact, in some areas they are required by law.
