What would you guys say the life expectancy of a walbro fp is? Non daily driver/weekend cruiser if that makes any difference.

Re: Just out of curiosity

If memory serves, mine has been in my truck now for a good 10-12 years? Been through all the motions of daily, sitting, and racing.

I will say though, during the times it does sit for long periods, its typically is low on gas (1/4 tank usually). Not sure if you want to say thats good because the hoses dont stay submerged and get soft and rot...or because it stays dry, the hose dries out and cracks.

It's crossed my mind to pull the bed and check out the condition of the hoses.

My Walbro is from 2001. My truck makes a decent amount of hp (~450). I contacted racetronix about buy a new one a few years ago, they recommended that I keep my 2001 walbro because they less prone to failure.

I have about 13-14k miles on mine.

Not sure why you are asking, but a few years ago there were several people having problems with counterfeit Walbro pumps failing early. At the time, a 'Walbro' selling for less than about $100 was a warning sign that it might not be genuine.

This... And make sure the hose inside your tank is rated for submersion..

I was up until about 5am wearing out the search engine on why the truck could be falling on it's face after a hard launch. Now I've got a checklist of things I'm gonna do before the weekend comes. There's an 1/8th mile track day coming up this Sat and a friend of mine with a modded Cherokee SRT (who never met up to run me last year) is finally going to the track, go figure. I really gotta stop dicking around and get a Datamaster.

Fuel pump is probably 10+ years old. I did hear about quite a bit of Walbro's failing. Were most of those Ebay knock-offs I assume or were they actually genuine Walbro that were failing? Either way mine's an oldie.

How exactly is it falling on its face? The engine cuts out or it does it not accelerate like you think it should?

Re: Just out of curiosity

One way to know for sure if it's the pump, or a loss of pressure by the fuel sloshing rearward on launch: Put a pressure gauge on it, snake the hose out from under the hood, place the gauge under a wiper blade so you can read it through the glass, and launch it. If the pressure drops, then comes back up, it's an in-tank problem. Add fuel, and try again. If it still does it, probably the pump.

I'm not sure what the knock-off failures were like, or how long it took. Genuine Walbro failures are like <1 per hundred. Ron Gregory has some failure stats on his site. If it's running 10+ years later, its probably genuine. Nothing from China lasts 10 years.

I did read that these trucks have a fuel sloshing hiccup if there's not enough gas in the tank.

Re-tracking my footsteps I bought about 5 gallons of race gas and showed up at the track with probably less than an 1/8th of a tank. Must've figured the less blend of street/race gas the better I don't know. I probably made 7 or 8 passes because it wasn't a busy track day. And coincidentally, it was the very last pass when the launch felt really good and it was as if my key turned off at about the 60-100ft mark, maybe shorter. I drove almost 70 miles on the way home before having to fuel up (going about 70-75 on the highway). I am running 60lb inj with a Walbro255 so it's sucking some fuel.

We hooked up a FP gauge to it early last year and everything checked out okay. I never launched it though. Just 15mph roll out and wot. Since the gauge was a rental and didn't want any oOps. Shit this is probably sounding like someone running their fingernails across a chalkboard to most of you. That probably was my problem.

It sounds like 1/2 tank or better is what a lot of guys live by on here.

Re: Just out of curiosity

If you were running less than a 1/4 tank, there's a good possibility that may have been the problem.

I've had the fuel slosh issue with upwards of half a tank, but everyone fuel gauge may read differently. I don't race unless I'm above 1/2.
