<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Supposedly, legend has
it, the Typhoon and TTA pumps were the best of the breed, but I can tell you
from personal experience that my TTA pump was constantly starving out, even from
the first day I drove it new in 1989. All the eventual versions of
adjustable-FPR never helped me on the top end. </FONT></DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4></FONT> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>As for the Typhoon
stock pump... I haven't driven it enough to give an impression....</FONT></DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4></FONT> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Since you're gonna
rewire that harness-- a bit of a romantic exercise in ultimate futility (like
cc-ing your heads) unless you're installing a true high-amp pump(s) in a
first-gen Grand National, which isn't necessary for street/strip-- you might
want to consider the viable alternative of retaining the stock wiring and
splicing-in one of those Boost-a-Volt (or whatever they call 'em nowdays)
on-demand overdrivers for the FP. I got one from Kennedy-Bell and it
RESURRECTED my stock-schlock Bosch TTA FP. Too bad I never got to drive it
much before I tore the engine down again....</FONT></DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>I'm tempted to install
one (basically, a 13-to-18-volt DC-DC Converter which is enabled by a
boost-switch) on my 'Clone but with that fat Walbro 255 in there now-- which
never chokes or starves-- I'm not sure it will do much good for the cam and
injectors I'm currently running. Your plans might be different....

<DIV>I had originally thought the FPR to be the culprit, but confirmed the pump
problem using the technique you (and the GM manual) describe.</DIV>

<DIV>You seem to be suggesting that the OEM pump is already a Bosch? If
so, I'll definitely go Walbro, but based on last year's flurry of messages on
the subject, I'll likely spring for the extra bucks and wait-time to get
Racetronix' plug-n-play harness as well.<BR>

based on a lucky eBay purchase! That thing will put out over 93psi with
my FPR cranked-in all the way-- and before further diaphragm depression from
turbo boost! I'll never go back to Bosch!! I recommend you
don't either. Be not afraid! That extra pressure/flow will be
there when you most need it... and may well save your pistons during a
full-throttle blast in peak-summer weather. Check out the offerings on
eBay under "Syclone Fuel Pump" for the best deals vis-a-vis regular Internet

I've yet to publish my unique troubles with my "fancy" FPR-- which went BAD on
me at the onset of cold weather here last November-- you might want to VERIFY
that it is in fact your FP and not the FPR that is causing your woes. I
was struggling to run with only 11psi when I finally broke down and rigged-up
my fuel-pressure hose & remote gauge. I was heartbroken. All
that grief pulling the tank and the Walbro let me down...? But, the
actual culprit was a collapsed FPR diaphragm. As soon as I switched-in
the old mechanically adjustable FPR I used on my T-Trans Am (never throw away
your "obsolete" performance parts!) we were back in business... never a speck
of trouble since then! Check out your start-up/idle pressure (no need to
start the engine) by CLAMPING THE FUEL-RETURN LINE with a pair of needle-nosed

<DIV><BR></DIV>The Ty's OEM pump is down to about 25 psi. The poor thing
barely runs. I'm pumping and pulling the tank tomorrow. There was
a lot of talk about Walbros in Feb. '05, but I'm not planning on racing,
except the occasional stoplight Grand Prix. I'm leaning towards a Bosch
replacement pump. Advice is welcome.....particularly if it comes from
the one and only serovilo, grtyphoon, bullyhart, merk1993 or any of the other
great contributors.<BR>
