looks like the fuel pump has about had it

[84BuickGNYorkPA]

Right here I got a backfire, 60lb injectors, I don't recall ever having inj duty cycles this high before. This was a short stab into the throttle.. here is the file (frame 3628) if anyone wants to have a look, it's rather boring street driving. Running SD2 here is a screen shot to temporarily set your parameters.

I wonder about the alternator being on the low side also....PSI 4 is the fuel pressure.

 

[Steve V]

Psi4 is that fuel pressure? If so yes sir I agree the pumps done if the regulator is ok.

Hi Steve,

Yes sir that is the fuel pressure...

Hi Steve,

Hi Chuck,

I agree with you.

What pump?

 

[84BuickGNYorkPA]

What pump?

Racetronix G75 or Walbro 340 ?

Racetronix G75 or Walbro 340 ?

50psi at 22lbs of boosttime for a new pump.they cook fast with no fuel pressure

I just don't trust the Walbro's anymore, after going through 3 of them. 2 not lasting more than a couple of weeks. I went to a GM pump after the Walbro's gave up and that lasted for 3-4 yrs, then just last year I went to a DW 300 cause the GM pump wouldn't deliver at over 23 psi boost. The DW has been a great pump so far.

Yea, I'm searching my options now on here, looks like many are going with the DW 300 pump. Some are saying the return line might be too small and need upgraded. This pump has lasted a few years, so I can't complain about it. I see Nick in Arizona has some really nice set-ups, but I'm not looking to drop that much money.

He can get you a DW to drop in. But imop just do it right the first time it will save you down the road

If there was more corn fuel around my area I would think about pulling the trigger on the $500 new fuel lines from RaceTronix which would give me the added volume for the DW.
