How To Rig Bleeds

#1 Post by stroker1 » Fri May 23, 2008 11:18 am

Does anyone have a pic of how the bleeds are rigged at the solenoids? Or have a part list or a site that sells them already rigged up?

A friend of mine is having pressure drop issues on the fuel side of his fogger. One stage is a plate and the fuel side on it does fine. Same pump runs both plate and fogger. He has tried new pumps, new regulators, dead heading, and return style. Also different gages. He sets the flowing pressure with a big hand held fuel pressure gage. But after you switch off the pump, and then cut it back on it will drop and not recover until you purge the fuel solenoid. Also it will drop pressure while making a pass.

Can't explain it. Same set up on the plate shot does fine. But on the fogger shot the fuel pressure acts stupid. Really only difference is 2 fuel solenoids v/s 1 fuel solenoid. I thought about asking him to try a .020" bleed at both solenoids to see if it would help. What ya'll think? :roll:

I went out and took some pictures for ya, this question about bleeds comes up often so I added an article to the tech section. Let me know if you have any questions and I'll update the article

I will post up a pic of the fuel log I just made and the other fuel upgrades I made as soon as I can get to the car. But basically the bleeds are just like the ones in john pics. I got the jet dimensions for the carb and nitrous bleeds from the diagrams on product engineerings website.

Thanks guys! That does help alot! Yeah, Sunsation 540, it is a dual regulator for the plate and fogger. Just same pump. And BG regulators I think. But he has tried multiple regulators both dead headed and return regulators. Nothing has fixed the problem so far. Maybe the bleeds will fix it.
