This latest post took longer to compose than it took me to install
Walbro in-line fuel pump #3!
To listen to the fruits of my labors, click HERE!
... at this point I was pleased but, recalled the same results when
I installed Walbro#2 just 4000 miles ago)
Next item of business, check the voltage going to the pump
(as everyone at one time or another has suggested I do that...)
visual evidence of THAT test is HERE!
Although not a "FAT" 12 volts, I don't think the pump was
"starving for voltage" but, then, what the freak do I know?
Just about 11 minutes into my testin of my newly installed
Walbro pump, I thought I heard a sound... yes, I DID hear a
sound... to hear the sound I heard, click HERE!
Fingers crossed the noise doesn't get louder but, with my luck....
My testing continued. To see what the voltage drop is when
the engine's cooling fan turns ON and OFF... click HERE!
Finally, another problem rears its ugly little freakin' head... as
you recall, I had an adjustable fuel pressure regulator installed
a few weeks ago and set the fuel pressure at 38 psi
(as recommended by "those in the know").
This past Saturday while at the track, I noticed the pressure
had dropped down to around 30 psi so, I bumped it back up to
where it belonged... Keep in mind, my fuel pump (Walbro#2)
was on the verge of total failure so, in retrospect, my confidence
the pump was putting out steady pressure, was not 100% so,
today, with a brand spankin' new Walbro pumping it's little
heart out, I checked under the hood and sure enough, the FPR
gauge was reading around 75 so, I began turning the
adjustment screw and the pressure got lower and lower and...
well, just take a peek HERE to see why I hate working on cars!
From the Department Of Grasping At Straws: "Is it possible, the
return line is too small to return all the unused fuel, causing
pressure to build up in the system?
At this point, although it's not a Chevy, I feel very tempted to
drive it to a levy and wait for the flood season!
