2-3 PSI.
Carbs never need more than that. Any more Fuel pressure and you will see the carb start spitting fuel out... I think the last time I did carbs I went to AutoZone and bought whatever I found...by that statement I mean...I dont really care who makes it....its a simple electronic pump... To me, being able to find one on sunday is better than the name on the side of the pump... The regulator is a different story for me...high quality, easy to set, and leak free. Order that, get one from Summit or a local race shop. Get a really good one. Rich |

[/quote] here is the first one... is the fuel regulator from the d-jet usable on carbs? i have 3 of them rich [/quote] Nothing from the FI fuel pump nor regulator can be used on carbs. FI pump puts out 65 PSI. FI regulator drops is down to 28-32 and car go to 40. Carbs Fuel pump is 1.5-3 PSI. Carb regulator is 1.5-8 PSI normally. (in that range) the carbs regulator cannot handle 65 PSI input..it will leak right away and become a boat anchor in seconds. the FI regulator will not go down low enough for carbs and then you will shoot fuel out the carbs all over the motor... You need to buy two cheap items. An elec fuel pump, and a regulator. Rich |
