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.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
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.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 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 just did a big write up on the Walbro.
I agree. Doesn't make sense to me either.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.
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).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.
Was he running 2 Walbro pumps, or just one at the time?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.
