<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>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.... </FONT></DIV>

<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>

<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>
