Massive fuel leak somewhere on the driver side fuel rail.

[78F350]

I'm working on a car that sat for many years. To get it running well, I had to replace the fuel sender and pump, fuel filter, and rail with injectors. (Plus remove all fuel, replace some of the coils, spark plug tubes, water pump, a radiator, heater core... still lots left to do.)

Removing the fuel rail does require some work. Here's a tech article from Pelican Parts: https://www.pelicanparts.com/techarticles/Boxster_Tech/25-FUEL-Injectors/25-FUEL-Injectors.htm
There's some good info there, but it does not say anything about removing the intake and all of the pictures show the engine OUT OF THE CAR.

A simplified list of what I remember:

• Disconnect most of the engine wire harness.
• Remove air filter.
• Disconnect crank case vent at front left of engine.
• Remove left side intake.
• Remove Secondary Air Injection Blower.

Now you should have space to access and remove the rail, but it is still tight.



While you are there, it would be a good time to consider changing spark plugs, spark plug tubes, and inspecting your coils. I can upload a brief video discussing it, but I expect there are already some better ones on YouTube.

Thanks for the replies. I've read the Pelican write up, but they go into more detail about cleaning up after yourself than they do getting to the fuel rail, lol.

I ordered a Bentley manual this morning, that Hopefully covers more information. Sounds like there's some real work involved, and I'll have to take a look into replacing some other stuff while I'm in there. Surprisingly enough, it still started right up, even with the 2 year old gas in there. So I think I'm probably in better shape than most would think for a car that "sat for years". It really only sat 24 months since the last time it's been driven, and I was driving it daily then.
