Guys, John, Jason, james....Anyone

I just started to hear a loud whine coming from the V3......I have about 500 miles on the system........Is this normal.......I assume its the fuel Pump.

Thanks for any help on this.

How much fuel is in the tank? The reason i ask is because the older V2 systems would whine loud when they were sucking air.

I have Just under 1/2 a tank.....No green light flash or change in performance at all.......

Check the pre-pump screen.

Check the pre-pump screen.

Hey this is a great time to be able to check pressure so we don't have to guess whats going on! Do you have a pressure guage?

[Jed196]

I do not have a PG yet...I guess I'll be buying one today though....I will check the screen and pressure tonight....



thanks.

If you have a tire pressure guage that reads up to 80 psi, that will work.

Yep, and they're only about $6 (or less) at your local auto parts store.

Guys,

I'm having trouble finding a gauge that goes to 80 lbs. I just order the injector pressure kit from Harborfrieght, but I gotta find one now. tried all local parts stores, even the performance shops. All the cheap non-screw on jobies only go to 60lbs. I guess I should have picked up all necessary tools before goin down the road....I'm learning on the fly....by the way, when I check my screen, should I clamp the veg lines to avoid loss?

Go to a truck stop,all Big Rigs run between 85-130 PSI there a little more $15-$20? but I've had mine 15 years

As Greasy mentioned, a truck stop would be a good place to check. Also, an RV store would be good as well.

I found mine at the local Autozone. They had a variety of models and many of them only went up to 50 or 60psi. The one I went with was labled for "Trucks and RVs". I think it'll go to 120 or 150psi. $7 later I was out the door...

Do you guys have Autozones up there? Maybe Advance or NAPA might have something as well.

A last resort would be to rent a fuel pressure tester from one of the parts houses. I know Autozone had one that I breifly considered renting. They even sold the same model and I think it was around $40. I didn't buy one cause I plan on picking up gauges soon. And the only other car I would need to check would be my Camaro - it's got a gauge under the hood on the rail.

Thanks!

also check valve for anything obstructing it from seal completely,sometimes you can't hear it but you lose pressure daily{thats why truckers check pressure daily high pressure leaks easier}.Don't overlook maybe faulty schrader valve(it happens).Good luck

Noise from these things is pretty unusual. Something simple to check would be the isolators, the filter and the actual manifold itself. If any part of the Manifold or filter is touching the frame or body it will transmit the harmonics into the cab and cause all kinds of noise. If the Manifold is not centered just right, there is a good chance of the filter itself hitting the outer body. Also if one of the Isolators were to break, come unsecured somehow this could also caus the manifold to shift and make contact. Hopefully something simple like that.

Hey jason remember my pump issue(NH),maybe same thing?

[Jed196]

To follow in my issues.

I still dont have that pressure value, but soon after the post the whinning mysteriously stopped. Shortly after, my filter went, so I changed it check the pre-screen, pulled the check valve...all was in order...it appears that the culprit was the filter........I understand it is common for the first filter to go at around 800 miles. Can anyone tell me why?

Thanks for all the help !!!!!
