[Syty] Fuel Pump

[DOlivares]

Is that a real car-lift or a couple o' pair o' jackstands (cinder blocks if you're in Appalachia or Arkansas)?  Do you have your own... or access to a private 'lift?

I'm still gonna put one in my garage when I get a few bucks ahead, but for short, day-long jobs I have a pal who'll lend me one of his commercial 'lifts.  But, he sure doesn't like over-niters... who does?  ...makes things tense at times.

There's NOTHING like having your own!  I got spoiled those 14 years at NASA.  IF you do in fact have your own car-lift in your own garage...

I WANT YOUR STREET ADDRESS RIGHT NOW!!!

Enviously yours, 

Dennis O.

Alrighty then.  I suppose that also explains why the OEM pump is so quiet.
Well, I'm going to be a Walbro convert.  'Specially since Daron saved me around $200 with his 'how to' on the hangar tube I destroyed.
While I've got that tank out, it looks like a golden opportunity to replace those leaky OEM airshocks too.


Good thing I've got alternate transportation while that Ty is resting comfortably up on that lift.

  You're welcome Dennis.


  I only considered the Bosch 'cuz it's obviously better than GM and locally available for the quick fix.  Everyone (except "Ron") seems to like the Walbro, and although those "dissertations" about fried wiring scared me, the Racetronix harness seems the easiest, though more expensive, way to go.

    Thanx for the advance-vote of confidence, Jeff,

    But so far my experience with Walbros versus stock-Bosches strongly favors the FORMER.  And now that I think about it,everystock-Bosch pump I ever owned has been high on longevity but POOR in providing that nice neck-snapping PRESSURE needed for smooth full-throttle response.

    Price-wise, they don't compare well either:  Putting that Walbro 255 in the tank (sans "pulsator") this past Summer only cost me$69 delivered 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 providers of Walbros....

    Although 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 vise-grips or something equally positive-gripping.  If you still get the same low readings IT IS THE PUMP.  But, if the pressure goes north of 40psi, you've just saved yourself a lot of money and/or acrobatic labor!

    Good luck,

    Dennis O.

    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.
