I just took my car in for it's first oil change, and desided to have my friend check the fuel pressure. It was at 36psi. We decided to adjust it to 46psi, because the engine has a lot of mods. On the way home I noticed a strong gas smell, and the car would hardly stay running. I got home opened the hood and found out that one of the hoses on the pressure regulator had come off and gas had gotten spewed all around the back of the engine. The problem is after I decreased the pressure, by I'm guessing around 6psi, the car wont start up and it seems to be making some kind of gurgleing noise. What's wrong???? I need to leave for work in a few hours and this is my only means of transportation. Please, help.

 

Joe,

Obviously, you'll have to repair the burst hose. Then adjust it back to stock pressure (where it at least would run).

Next, list your modifications and settings so we can have an idea of what the appropriate fuel pressure might be. Even then it will only be a guess, and you will have to do some experimentation to get the ideal setting.

I set the pressure back to where it was before by turning the screw in the reg. about an 1/8 of a turn counter-clockwise. So it should be around 38-40psi, or where it was before. My friend, who works at Goodyear, just left town for a week, right after I called him and told him I smelled fuel as I was driving home. I tried calling him back when I found about the hose and he had already left, so now I don't have access to a fuel gauge or my friend who built the engine. Now about the hose, do I for sure need another one? I thought that this one had just come off because the fuel pressure was too high. Also why would it come off at only 46psi? Is there a clamp that goes on the hose, also? I connected the hose on and the car still won't start. The engine is a 355, hot cam, vette heads, 10.25:1 comp, just about every thing else is modded also, and I should be getting my custom PR chip today or monday.

 

CJ, it would probably help if you explained which hose. Is it the little one that hooks up to the regulator and plenum? If so your regulator gasket has just **** the bed and it's time to replace it, no biggie. If one of the fuel rail pipes burst, that is some bad. Let us know.

Yeah it's that little hose, with a 90 degree boot, that connects to the back of the plenum. I'm just wondering how that gasket could be bad, when it's only 3 weeks old. Also, do I have to replace this gasket in order to drive the car, will it keep throwing gas everywhere if I dont?

 

Replace the gasket, don't drive it. Just make sure you have everything you need to do it, get a ride to the stor and back; 1/2 hr. job. Good luck.

 

Thanks, I'll probably have to wait until tomorrow to replace the gasket, now I just need to somehow found a ride to work. Thanks again.
