would 30 gph be ok for my V8 ?? Be careful when you look at pumps. It may deliver 30 GPH but that's not at 3 psi. At 3 psi I bet it puts out only 15 GPH like the facet. Remember that fuel = hp. The facet says it's good to about 150 hp (IMG:style_emoticons/default/bs.gif) . If your V8 is making only 150 hp why bother with the conversion at all. The Holley HP 125 flows 110 GPH at 7 psi. Its good for about 700 hp. |

I had a facet on my carbed motor. Hated it. Noisy, didn't perform well. Put in a Pierburg (I've been told that it's the same as a CB Performance) & had no problems. Please don't try & use a stock pump, I'm very sure it will end badly.

Had her out today again for about a 40min run. The Facet pump and Holley fuel regulator are both working like a charm. With the new Weber dual 40 IDF carbs, the car idles great around 850-900 RPM, pulls strong to redline, and also is smooth with no stumbles nor backfires. Did a lot of back roads today and also a 15 min highway run at up to 75mph. I am a happy camper (IMG:style_emoticons/default/biggrin.gif)

i can't wait to send my car in for a near total restoration. it really needs everything else too. -- Had her out today again for about a 40min run.

I am running the old Bosch 009 with points elimination (electronic ignition module) from Hot-Spark.net. While I know that folks constantly complain about this distributor and claim a bad flat-spot off idle, my car does not have this problem. Coming off the line at idle from a red light or stop sign (even up-hill) is NO problem. The GA 2.0 flat four revs quick and smooth, all the way to redline. No hesitation, misses or backfires. My shop spent a lot of time sorting out the car over the past few weeks to include valve adjustments, compression testing (150-155 across all four cylinders), full tune-up (plugs, cap, rotor, wires, dual fuel filters and timing), new fuel system/dual Weber 40 IDF carbs, and we added 40mm velocity stacks from CB Performance before tune/sync as Redline-Weber does not include stacks with their 40 kit. We also did the stainless and new rubber fuel lines, throttle cable and pedal bushings, so the throttle action is smooth and snaps right back to idle with no issues. Also cleaned up the electrical system including new positive and negative battery cables with neg-disconnect switch, all new connectors at the coil, cleaned up the relay board, new voltage regulator + a new Bosch hot-start kit for the hot summer months.
The car will be back home early next week. I will take and post some videos of the car at idle, coming off the line and on the road to share. Good luck with your project, I know that I made the right choices for my setup! |

What about this for a fuel Pump?
http://www.tennesseespeedsport.com/MR-Gask...-Fuel-Pump.html Looks about right, 3.5 psi, no vapor locking it claims. I remember the 80's hanging out with my friend on the side of the road in his Fiat X-19 mid engined car waiting for the fuel pump to cool down so we could get it started again. |
