Walbro, remote dual filter install w/ pics

[Snoxracer]

So your saying that neither vehicle in the crash had an altered fuel system? I have never seen a bottom fill in any system. And how does the factory return line on our trucks work? I'm pretty sure they don't have a line running to the bottom of the tank.

Very nice install. After see your install I have been thinking about doing some thing like that now and getting rid of the retro fit that they did in 2005. I have had now trouble with. just low fuel pressures that for showing the really nice pics

Very nice install, I wish I had the room you had(mine is a QCSB) so my plumbing is not quite as nice, but almost identical.



Amen on Richard (GDP), very helpful man.

nice install, only thing I don't see is a pre-pump strainer. (like the one Richard sells. )

I almost burned up my Walbro by running a regular inline filter(not the strainer) prior to the pump. there is a small screen in the inlet of the pump that if it plugs will burn up the pump and voids the pump warranty. in my case the filter was doing the same thing as the pump screen.

TSPowell,



Nice install!!!



How did you hook-up your fuel pressure guage? Is it an all electrical system?



I installed the GDP/Walbro system on my '03 & like it. However, my original pump died after 11 months use. There was a short in the pump & it would just die. If you tapped on the pump, it would start, again. I had a spare pump & installed it.



Richard was VERY helpful both with my install & warranty coverage on the original pump. I would not be afraid to buy anything, from him.



At this time, I would like to install a Big Line Kit with a 2 micron filter (Caterpillar). I kept my stock filter & would like to install the Cat filter in between the stock filter & the CP-3. Don't have much room under the intake horn because of the APPS? taking up that space.

I like this setup, it is very neat and clean.



I may have missed it, but what did all the parts cost you?

Berthoud Pass , its beautiful there. By the way, thats a beautiful install. MOE

Thanks for the compliments!!

I did install the same strainer the Richard sells (Fleetguard FF5079 3/8" Inline Strainer) but I bought it from Cummins Rocky Mountain. In pic#2 you can just slightly see part of the filter/strainer as the supply line comes down between the tank and frame.

I put a Tee in the supply line about where the old filter mount was and ran it to my mechanical fuel pressure isolator by the battery.

I dont remember the cost. I pieced all of it together myself, bought the pump form ebay ($80), all hose and fittings from a Parker store that is close by and the rest from GDP.

Neat, clean and it looks well supported. Nicely done TSPowell.



Twest, it is good you brought the issue up. We all need to be reminded that before doing any modifications to our trucks we should give serious consideration to safety, durability and crash worthiness.



Your source of information though, a group of ambulance chasers, is suspect and prone to wild exaggeration. A good example is the GM saddle tank fiasco. That was a self feeding media and lawsuit frenzy rather than a faulty design. Plus we are talking about diesel here, which poses much less fire hazard than gasoline.



In this case, the return to the filler tube keeps the tank’s inherent safeties intact (ie rollover check valves, etc. ). The only negative scenario that comes to mind would be if the pump continued to run after an accident in which the filler neck was destroyed and the tank remained intact. Under that one situation fuel could be pumped on the ground where it might not have if the return was directly into the tank.



Also it can be argued that any modifications to the tank itself will likely pose more of a risk in an accident than the filler tube return does. This is because the stock tank fittings are designed to be crash worthy and keep fuel in the tank even when upside down. Aftermarket fittings do not come with ROV’s built in and depending on where and how they are installed they might be more vulnerable to damage during an accident.



One should be more worried about the popular tank vent modification which vents the very top of the tank to the filler tube, bypassing the rollover check valves. In a rollover, that vent modification will allow fuel to flow unrestricted out of the tank and into the filler tube, which if broken, will allow it to spill on the ground.



Again, nice work TS. Though neither are likely to be a problem, about the only concerns I'd have would be road debris hitting the filters and having the positive stud on the pump exposed.

Sorry to bring this back from the dead, but I'm wondering what size fittings these filter bases use? TSPowell, do you remember the tread type and size? I'm working on a similar project, but can't find the fitting size...

Nice setup !! My system is the same, just some locations are a little different. Richard was excellent to deal with and my system has been running without a glitch for over 2 years and 50000km.
