Will the stock fuel pump supply enough gas to run with RB carb setup? Just wondering if anybody tried this.

 

no, stock is about 3 and you need 6+

 

Thanks, I figured as much. Guess I'll get under there ad change it. Old age is making me lazy!

 

My 85 pump keeps up fine with my Dellorto.
As I recall, Racing Beat stated that the 84 and 85 fuel pump is good for WOT operation up to 5 to 6 seconds.

 

The Dellorto, or Weber's need only 3.5 to 4 psi to run. The Holley needs at least 5.5 psi. The stock pump from a carbed 12A WILL NOT be enough for either. If you have removed the fuel injection from a 13B, that pump will be too much without a return style regulator.

 

I put the racing beat setup on my 82 and the stock pump hasn't had a problem yet. Maybe because I haven't had her opened up too long.

 

for a Holley, you need a pump that puts out more pressure and more volume. period.

for the Weber (and it's knock-offs), you need more volume.

 

Would a blue holley pump be enough?

 

Red pump is fine but blue will work also with a FPR.
