Just curious about this. Have had my present Walbro on the car for over 5 years now. Am going to be updating my car here in the next few months and get a new tune. Is this something I don't need to worry about, or is it good insurance to just swap in a new pump since it's relatively cheap to do? THanks.

 

I wouldn't worry about it. As long as you have a WB O2 sensor and generally keep an eye on it you should be okay. I have heard them lasting longer than 5 years. Failures seem to be pretty random. Just listen for any increase in whining and keep an eye on the AFR's. Don't worry.

 

they are cheap to replace and after 5 years its cheap insurance i never had back seats in any of my cars so they were always loud and when they would start to get quiet after a few years i would just swap them i am not sure how fast there performance degrade but everythings has a service life.

 

How would I tell an "increase in whining" from a Whinebro?" LOL

Just kidding. Although it can get pretty loud at times.

My Innovate is shot. Thinking of adding a Zeitronix to the mix.

 

You can definitely tell when they get louder, like on hot days or whenever you are really running the car hard. Don't get me wrong, I am not saying don't replace it, I just think you will be fine for the time being. If you are not running a wideband then I would replace it just for peace of mind. If you are running a working wideband, then just keep an eye on it and you will be able to stop the car before any damage is done.

 

I've had mine for over three years now and no problems.

 

Erik - get a bosch....better and quiet...

 

Yeah I'm looking into a Zeitronix myself, I was looking at the DashDaq which is nice but its a bit pricey I think I'm just gonna get the LCD display.

 

quiet? not the 044. its much louder than a walbro.

 

just replace it. walbro's arent known for stellar quality and the $80 is good insurance.

 

There's a drop-in Bosch FP for the Evo?

 

not exactly a drop in, but im pretty sure an 040 could fit in tank.

 

I've had mine for about 3 years. No problems with mine at this point. I to was planning to swap it out in about 10K miles. I also believe in cheap maintenance. I don't always follow the don't fix until its broken philosophy.

 

Mines have over 40k miles and over 4 years on it, daily driven. No problems yet.

 

I only changed mine when I couldn't stand the noise anymore. But of course, I got my money out of it.
