I have been busy with life and haven't been on a diesel site in ages. Have any Walbros quit yet ?

Thanks.

I've been running mine for 4+ years on my Rock buggy with no failures. Only had them on the Dodge for a couple days, but I'm feelin' pretty confident they'll hold up... :thumbsup

Smart money is on putting the pump close to the tank, and getting a filter to go on the suction side. (I use a 10 micron Fram G3727)

I just did a big write up on the Walbro.

Dunno why everyone is so hot on the "Other" pumps that are harder to get than the stock intank one.. Guess it'll take someone spending a cold night or 2 on the side of the road to figure it out. Walbros are available everywhere.

Your rock buggy is a gasser, right ? Back in the day when I first started telling people about Walbros (December 2005), nobody but me had run one on a diesel. Lots of people said they would fail. How the times have changed.

If the pumping circuit gets plumbed up so that the fuel goes through a filter before it returns to the tank the suction side filter isn't really needed. Any debris that is in the fuel will get removed on the first pass. If you have so much debris in your fuel that it wrecks a pump on the first pass, then you need a new fuel supplier or you need filters on the supplier pump.

I just did a big write up on the Walbro.
I saw it. The dual Walbros was total overkill. A single Walbro will supply even the most extremely overfueled Cummins just fine. The 150 GPH that the other guys advertise is just a red herring. Unfortunately most people buy it. :sad:

I agree. Doesn't make sense to me either.

Cheers

I have been running a regular in line pre-pump filter before my walbro (a small clear filter that you can see through) and that thing clogs up quick. Is there any in-line filter made specifically for diesel fuel? The gas filter will clog and fold up and cause my psi to drop quick. I change the filter and it goes back up to 16-18 psi, but I am getting tired of changing it every other month.

Friend of mine has gone through 2. They'd hold pressure at idle but would drop to 0 as you increased throttle. He went to a different fuel setup. He dynos around 870hp on fuel only with dual cp3's. Another guy I know had his doing the same thing. He replaced it with a new one and has been fine ever since. They are an electric pump. They are going to go out. It's just a matter of time.

I'm going to try a Fram G3727. Basicly, it's a large 10 micron fuel filter they used on Chevy fuel injected V-8's. I'll let you know if it works out. (I'm thinking it'll be fine).

Was he running 2 Walbro pumps, or just one at the time?

Both were running one at a time. They weren't real old pumps either. Maybe 6 months old. One of them was bad right out of the box.

If it's mechanical, and Man made it, it might fail, huh?

Everything is prone to failure. Doesn't matter how engineered or special it might seem. If it's a mechanical component (granted this is an electric motor but I'm calling it a mechanical piece) it's gonna fail sometime or another. Heck, I just read of one guy's p-pump die on him and those aren't supposed to fail either but they do to (although that is probably 1 in 10,000). I'm a realist. You can spout off all the mumbo jumbo about flow rates and amperage ratings and load percentages and what not but all that is to me is numbers and I don't care what the numbers say, I care about what the real world says and the real wold says that these pumps have failed, they are going to fail, it's just a matter of when. It could be today, tomorrow, 6 years from now. Either way you look at it though they are going to fail. Nothing is fail safe.

Thread revisit:

Big Blue, sure, Electromechanical things fail. But SOMETIMES you gotta put a little bit of faith in the R&D that big corps. do... Small corps. struggle with R&D costs and....

I dunno.

I think I'll throw my hat in the ring of the PROVEN product, not the one out to make a buck and sell the corp to the highest bidder.

Call me old fashioned. I'm not sitting on the side of the road, though...

I have read allot about Electromechanical FASS and AD pumps failing over the years, EVEN now, couple current threads... "My XYZ pump left me on the side of the road, and I had to wait X weeks to replace it".

For the record, I STILL got the Walbros I originally installed... (I DID remove the second one that was in the article here... It really was overkill for me, but some people at the time were all about FLOW...) My spare pump is STILL in the toolbox, and actually, has the company of the one I removed...

These pumps are SO COMMON, it's any wonder why anyone would stray from them... Unless they want to wait to get a replacement, or LINE someone Else's pocket with cash. KIDS like to do that. Some will exploit it. It's called "Stupidity" if you are the "Kid". It's called "Marketing" if you are the "Company".

Backing up the thread resurrection from wildcat, I have 91,000 on my Walbro and it is still working like a champ.

X2 what carlsonr said about the fuel strainer pre pump....I believe it is a fleetguard FF7977. I replaced my 392 at @ 170k just so I wouldn't have to do it on the side of the inter-state some night. It's a great little pump for stock applications. HTH

What do most people do about the pickup in the tank? I know there are tons of threads about running out of fuel with 1/4 tank left. I always thought the Draw Straw 4 or 5 or whatever (the latest one) seemed pretty promising because it sucked from the stock canister where fuel is returned?

How do these pumps hold up to WOT on stock to slightly modded trucks(no 800hp injectors and triple pumps)? I assume you guys run lift pressure gauges....
