I plan to upgrade my fuel system with 1/2" lines and a new Mechanical Fuel Pump and a new Electric Fuel Pump.

It appears that the Edelbrock Victor Race Pump is the only Mechanical Pump available with 1/2" NPT ports. (please let me know if there are others).

I plan to install an Electric Fuel Pump at the rear to supply extra fuel when using Nitrous. I do not want to run the Electric Pump full time. The Electric Pump will only run when Nitrous is activated. I have heard too many stories about Electric Pumps noisy and failing and leaving you stranded. I want to use a Mechanical Pump as my primary pump for reliability and noise reasons.

I plan to run 1/2"(or #10) line to the Electric Pump and then 1/2" line to the Mechanical Pump. After the Mechanical Pump I will run two # 8 or # 6 lines. One to a return style regulator (1/2" line from regulator back to tank) and to the nitrous system. The other to a "deadhead" regulator and the carbs. The Nitrous side will be run at a higher fuel pressure.

I am considering the Edelbrock Victor Race Pump because it has 1/2" NPT ports. I don't want it to be a big restriction when the Electric Pump is trying to push fuel thru.

Will the Edelbrock Victor Race Fuel Pump be OK for extended street driving?

Thanks, Joel

PS. Please don't tell me I need to run two separate fuel systems. I have read extensively on the topic and WILL use the type of system I have described above. I just want to know if the Edelbrock Pump will be reliable for long term street use.

Holley also offers the same pump in 1/2" npt inlet/outlet. They appear to be the same pump other than the name.

Will the mechanical pump pull gas through an electric when it's not running? Even if it pulls enough to run the engine it has to be a BIG restriction. I would really research this first.

Good luck.

I have talked with a couple people who are running very similar setups without problems and they are using Mechanical Fuel Pumps with ports that are smaller than 1/2" NPT.

If the Electric Pump acts as too much of a restriction (I don't think it will) I can always wire the Electric Pump to turn on any time the trans kickdown wire is energized.

I will need to do some research to make sure the Electric Pump that I choose will allow fuel to be pulled thru it. I was thinking of using a BG 220 HR Pump. Does anyone know if they will allow fuel to be "sucked thru them"?

Thanks, Joel

My Edelbrock victor pump just turned it's 20,000 mile. Not an amazing record, but it should hold up just fine. It is basically built like a stock pump, only better. You shouldn't have any problems ... and as you probably already know, you need to run a regulator with this pump, it puts out 14-16 psi.

Also, the Holley and Carter pumps are identical in every way except for their stickers. Their "race" versions also have 1/2 NPT ports. The diaphrams are interchangable and everything.
