Hi guys, first i had some trouble starting my van a mounth ago so I play a little with the carb but than realized it was my fuel pump so I changed it. The thing is the out side pipe still leaking a little bit (dipping).

Now the van is hard to start when cold ( mostly need to drop some fuel in the carb by the top), but when it is warm this is not too bad, it start well. Moreover, when I pushed fastly or hardly on the paddle the engine when to shut down and I heard a like a windy noise, like a vacuum.

Do you think that my leaking can keep my fuel pressure too low to run properly? Do you know what should I tune on the carb?

Thank you
Kevin

 

First, you don't give us any info about what you drive
Second , you say your car is hard to start, then in your post you say van but your profile says you drive an F-350.
You sound confused.

 

Hi Kevin,
Your van is 34 years old, you have a fuel leak, and you are pouring fuel into the carb to get it started. This is not a good time to learn about adjusting carbs. You should take it to a shop and get those problems solved, then spend some time learning about car (van) repair.

Need to fix that fuel leak before the whole thing catches fire. Once that's done, then address the carb's issues.
