[Syty] Fuel Pump

Fri Apr 21 14:00:13 CDT 2006

Many an adventurous will ATTEMPT mandrel, full-radius bending with conventional shoes, dies, and rams, but they usually end up kinking or tearing the stainless.  Pretty good job if you wanna go mild-steel... and then change 'em out every 4 years or so.  

Regular steel 3" pipes on small-puffing engines like ours won't get and keep the tubes hot enough to bake-off all the water that splashes up, condenses overnight or comes through with combustion gasses.  3" pipes are just too much of a heat-sink for a low-revving small-cubes motor.  My Zoomies only lasted 2 years on my dual-exhausted Gremlin with 2.25" pipes; they literally FLAKED to pieces!

I hear you.  The guy I found has good tube bending equipment, but the ECM occupying the 5" between his ears is apparently missing a few capacitors and resistors.
I need to hook up with some local rodders to see where they get their tubes bent.  That's yet another rainy day.

  Competent workers in 3" stainless are few and far between...

  and most outside Florida, California, and one Dallas outfit don't have access to the proper mandrel-bending jig required to do a true quality job in the first place.  I was gonna dump my Borla set-up on eBay (got like 11 bidders in 2 daze!) in favor of a custom-bent/hung job (topped/tipped-off by a Super-Trapp like I put on the TTA) that I was so sure I could procure at any racing-exhaust joint.  I still have that 7' stick of 3" tubing in its original JC Whippany box! 

  Of course, I haven't trolled the Internet in the past 3 years for such shops.  Maybe things have changed for the better.  I know where to buy the hydraulic mandrel-benders but thus far haven't been able to arm-twist any local hot-rodder into making the investment.  Here's a GREAT business opportunity for some of the more adventurous among you...!

  Local word-of-mouth on such 3-inch-stainless specialists is still dismal too.  It seems mostly folks just cobble-up a system from pieces of pre-bent sections... kinda how I used to do in the caveman daze....

  Good hunting,

  Speakin' of exhaust and an RIP ATR, what's a guy to do?  My local pipe bender couldn't get a 3" to fit and did a lousy job of hanging the 2 1/2" (it bangs against the frame on certain bumps).

    My TTA stood up better to the Boost-a-Volt:  Already had a 140-amp alternator and Optima battery.  Results: NO MORE WOT-starve-outs!  Volt-boost comes in with the "Seventh-Injector" at 15psi....  Gotta get that thing off the cinder-blox... one of these daze....

    I still have one of those suped-up Bosch pumps, NIB, but I never was able to burn out my stock pump in the TTA for all the years I drove it.  However, whether I ever need to swap-out that pump or not, I'm not too afraid since I got rid of all that cross-tank restrictive exhaust system early on-- just like I dumped the spare-tire rig on the 'Clone-- to reduce weight and simplify under-car operations.

    As I remember from ATR's (RIP) old catalog, there was a progression of GM FP regulators and I think also pumps in those years. The GN, and then the TTA and finally the SyTy's. ATR used to offer the upgraded GM models as an upgrade to the earlier models. But then as far as fuel pumps go, Walbro blew them all away.

    As far as the Boost - Volt devices. I've been trying them for at least 10 yrs. The original versions, from BGC (Bowling Green Customs for the younger guys) used to say U could crank them to 17 V. OK - I tried that on my TTA and blew out my Alternator and stock Fuel Pump. If U know anything about TTA's, I don't need to tell U how much work that made for me. I pray that I don't have to put another fuel pump in my TTA. I'll drill a hole in the top of my gas tank before I do another one!

    From what I hear, the newer versions on Volt Boosters limit the top voltage to 15 VDC.
