My walbro is making more noise than what i can remember.

What is the best/easiest way to measure my fuel pressure while under load?

I am running a stock fuel rail, stock injectors & pressure regualtor.

TIA

 

A fuel pressure guage? Did I miss something?

fuel pressure gauge. I don't think there is worst and hardest way to measure that, unless you make something at home out of stick of gum, floss and swiss army knife.

 

Yeah, a fuel pressure gauge......Good idea. Never thought of that.......

Yes, the "easy" aspect of the question.

Where do you "easily" tap into the fuel rail then?

I didnt see any bungs where i can tap into the fuel rail easily.

I can make a o-ringed block to sit between the fuel rail & fuel supply line, then drill & tap the block to accept a -3 line to go to a gauge, but that doesnt fit within the "easy" category.

i was hoping someone would might know of an easier solution....some software tool that may plug into the obdII port

That's easier in my mind.

Thanks for the insight

 

From what I know, there is no factory Fuel Pressure Sender, therefore tapping into the OBD port can't do anything for you.

Most people mount their Fuel Pressure gauges directly on the Fuel Filter. This doesnt help you measure the pressure in the car under load though.

This stuff would work...

Also check your fuel pressure at idle and part throttle cruise. We sell the Walbro GSS317 and GSS342 High Pressure and have seen some issues with the High Pressure model overpowering the stock fuel pressure regulator when the engine doesn't need more fuel.
We recommend the regular pressure for enthusiasts concerned with emmissions testing and not making insane amounts of power.

 

Pruven Performance and (I think) Ultimate Racing make adaptor blocks or the fuel rail inlet. I have the Pruven one and it works fine. I think this is the easiest/cleanest way to do it.

 

It would be interesting to see what is going on with the pressure when the pump gets louder

 

Thanks for the tip's.

This sounds like a possibilty.
