The bog is noticeable at 43.5 psi (stock) and makes it difficult to easily coordinate the clutch and gas when starting from a stop. Unless I carefully pedal it off the line, it will stall. I plan to increase the fuel pressure to make it better. It's my goto solution. In addition, the driver's seat b...

This is the one I have: https://www.amazon.com/gp/product/B000C ... UTF8&psc=1
It has special bracketing to mount to the LT1 fuel rail. The gauge is extra.

We pulled out the fuel sending assembly to replace the fuel pump and noticed a blown out hose that attaches the fuel pump to the rest of the fuel system. What a surprise! This explains the 5 psi on the fuel pressure gauge. Too bad I already bad-mouthed the Delphi fuel pump. It was doing it's best to...

Maverick called and urged me to jumper the pump directly to the battery, so I did. I saw similar symptoms. The pump puts out only about 5 psi. The order is in for the Walbro.

I did a bit of diagnosis today. I put an ammeter on the FP fuse and turned on the ignition. The meter went to 2.9 amps and then to zero in a few seconds. The FP gauge quickly registered 5 psi, then zero. Then, to check for some sort of blockage in the fuel system, I removed the output fuel hose from...

It's exciting to know that your Vette is back on the road. Not so much that mine is out of commission and back in the garage.

ODO: 104016 I took Silvia out to pick up dinner this evening. She was running perfectly with the fuel pressure set at 46 psi. On the way back she just quit. I took a quick peek at the fuel pressure while on the side of the road and it was ZERO when I turned the key on. Could it be another failure of...

ODO: 103989 On Tuesday, I took Silvia out to stretch her legs. On the way, I noticed that a "Check Gauges" message had appeared on the dash. This is a warning that the PCM puts out to tell the driver that it had detected an issue on one of the gauges. I looked over them quickly and could n...

ODO: 103940 I drove Silvia in actual Raleigh traffic this morning and the throttle response at the recommended fuel pressure of 43.5 psi proved to be unsatisfying again, so I started to incrementally bump up the fuel pressure. Each time I added 1 psi, the drivability improved. When I got it running ...

I was told by a Delphi customer service rep that their fuel pumps have a limited lifetime warranty. Just FYI.
I guess they realize how bad they really are.

First the noise: This one whipped my butt. I had to remove the underbody X-braces (convertible only) to find the problem. One point on an X-brace was in contact with an exhaust pipe. Over time, it would have worn a hole in the pipe. Good thing I felt/heard it. At a higher level, it was a question of...

What a beauty! Nothing like a red Corvette convertible.

I've been assessing the problem of losing fuel pressure after the engine is shut off. Over time, it appears that the loss of pressure is slowing down. In other words, the pressure is holding longer than initially. Over night, it goes to zero, but it will start rather quickly in the morning. If I hol...

I think this new fuel pump has a problem. I notice that the fuel pressure starts dropping rather quickly right after the engine is shut off. There is a check valve in the fuel pump that should prevent this. I called Delphi tech support and got a guy who actually understood what I was talking about. ...

What brand of fuel pumps are you using?
