a couple fuel/injector questions Im putting in an MS3 cam and planning on upgrading to 42# injectors. My question is am I going to screw stuff up by driving it untuned to the tuner shop? Ittl be about a 150 mile drive. Ive got a trailer and its no problem to trailer it just wondering how hard on it driving it would be.
Question number 2 is I noticed that I have a teeny fuel leak on the front of my drivers side fuel rail where that little black plastic cap is. Its oober slow and I just noticed it. probably makes one drip ever 3+ minutes.
car is my 2000 camaro LS1
I would search but its been broke for 6 days now...
thanks

I wouldn't drive it. When you smell how rich the car is going to run with those new injectors, you'll agree. When I upgraded to 60# injectors, the cloud of smoke when I pulled the car onto the trailer was awe-inspiring. And, I didn't change my cam or anything else in the motor. If you're going from a stock cam to an MS3, the car probably wouldn't run worth a crap even with the stock fuel system.
If the fuel rail is leaking, then the Schrader valve in there is bad. You need to buy a Schrader valve tool to remove the old one, and replace it with a new one. The cap itself does not seal the end of the rail.

I don't think that an auto parts store would have one. I've never bought one, but I'd expect an air conditioning supply place to have it. Schrader valves are used a lot in A/C systems.
Also, I forgot to mention that it's possible (however, unlikely) that it's just loosened up and isn't actually bad. I'd be a lot more inclined to believe that the valve is bad, though.

The valve is easy. The tool is a couple dollars at AutoZone and you can go to a tire shop and ask for a spare valve stem. It's the same little thing on the inside.
Hopefully that is the problem and not a crack around the fitting.

Shraeder r&r tool for cheap...
Goto the tire shop, and pick up a couple used tubless tire valve stems, and a couple caps w/ the removal "tool" on the end. Put a drop of Loctite on the stem threads, and tighten the cap on.
WALA!! A neat tool for the tool box, and a spare.. all for free.
Wouldn't hurt to buy a couple new valves, and include them in the box. [I have mine in an old fuse box].

just put the valve in and it fixed it! we had a valve stem tool at our shop so i used that. didnt put any loctite on it tho... ill do it tomorrow. should i purge that that valve a few times when the system is charging to get the air out before I start it?
