Just returned from a 4000 mile cross country trip with my camper. Several times when in Texas, i had of fill up with Bio Diesel, not my first choice, but i needed fuel. Coming home with about 100 miles to go i started to experience a loss of power when going up hills. So the first thing i did when i got home was to change the fuel filter. My son had a similar problem when he used the Bio Diesel. Clogged fuel filter. It looked pretty black when it was removed. Now the truck runs fine again. As i had purchased these 3 new filters a few years back, and this was the last one. I really can not remember where i purchased these filters, old age i guess. The number is FS 19598. Where do you folks purchase your filters

 

Genos Garage.
I order all my filters in bulk, shipped to my door.

 

Second on Genos.......

 

I was able to run full B100 without an issue (loved the smell from the trucks tailpipe), over two years. I transitioned back and forth from dino diesel and B100 for winter and summer.

I was worried about the filter too, but I guess I got lucky. I don't have a Cummins shop near me so I use Genos Garage as well.

Do you have a fuel pressure guage? And if you do, did your pressure drop too when the filter clogged?

 

You just missed a good deal at Geno's, they had a 10% off sale for the month of July on all filters. Seems as thou I'm not the only lucky diesel driver around. Geno's is great and fast service also.

 

Geno's is a great company. I've ordered numerous parts from them over the years.
But I'm no fan of Bio. They tried hard to introduce it when fuel costs were high but its easy to gel and its very corrosive. The highest I've seen it around here is B10 and I generally stray from that too.

 

I have tried not to buy Bio Diesel, last year I replaced my VP with a Blue Chip and put in an Air Dog, since I have been buying at the local Petro/Flying J truck stop here in Tallahassee at the RV pump.
About a month ago, I pulled up to the passenger car pumps and noticed a sticker saying that the diesel was a bio blend. When I asked the lady inside, she said that all they have been selling for well over a year.
Does anyone know for sure if Petro sells Bio, and where do I go to get high quality Dino fuel?

 

Check what they're selling. Its most likely B10 or B20. The "B" means bio and the number is the percentage of bio to ULSD.

 

I get Baldwins from the local diesel shop around the corner here. Geno's does have some great deals on fleetguards pretty regularly so keep an eye out, or just contact Robin and ask for the deal you missed....they like to keep customers!!

As for bio, it is a lot more slippery than dino and your vp probably loved it, but as stated it eats fuel lines and can be corrosive to other stuff. I only run it when I am cornered. I also go thru quite a bit of fuel so it doesn't sit in my tank for too long...

 

I love running it whenever I can. Down here in TX, I get B5 where I normally fill up. As noted above, it's biggest drawback is that is gels easily in winter time and nobody yet has come up with an additive to lower the cloud point like with dino diesel.

I would like to point out is that there is a difference between homebrew biodiesel and commercially produced biodiesel. Commercially produced biodiesel must meet the ASTM D6751 standards for quality. I have had zero problems running commercially produced biodiesel all the way up to B100. Have never run homebrew biodiesel though. Biodiesel can harm fuel lines made out of nitrile rubber (vehicles made in 1993 and earlier typically have nitrile rubber lines). Anything 1994 and later usually have Viton rubber fuel lines and handle biodiesel just fine. Our Rams have steel fuel lines with semi-flexible plastic tubing on each end to connect to the tank and the lift pump.

 

Yeah, I have always filled with commercially available stuff with no signs of trouble.

The fuel line I replaced the factory ss one with is the Parker blue stuff FASS sends with their kits so I am covered there.

I do know my vp is quieter on b20 than dino diesel!

 

If I remember right, some of the earlier aftermarket fuel system kits didnt come with bio compatible fuel lines.

 

I think you are right because I worried over that issue but took so long to get a FASS I knew the fuel lines were then compatible....

 

My owners manual specifies up to B5. I was in the Chicago area recently and was largely unable to find any fuel sources that didn't show "up to B20" on the pumps. On the way home I had to change my fuel filter when the truck became hard to start. The new filter ended the long crank problem. No fuel pressure gauge.

 

Bio wasn't around when the 2nd gens were in production.
