Lucas, Seafoam, MMO and others have a place in the fuel treatment hierarchy. I don't doubt they work in some cases but there is little magical power in them. ...

There's one aspect that I think is a noticeable improvement: Cetane improvers. My first Yanmar (1970's design) clanks horribly with straight diesel. It literally sounds like it has a spun rod bearing and will put a rod through the block at any moment when cold, only slightly better as it warms up. (Racket unchanged over the past 12 years, it couldn't be a rod.) I've read these were spec'ed for Japan's Cetane level which is higher than US fuel.

Cetane improver - Power Service Gray in my case - makes a very noticeable reduction in this clanking, brings it down into the range of a normal diesel, and seems to reduce smoking as it lugs down under load.

I'm convinced this Cetane-improvement aspect is real for that tractor. All the other claims ... well maybe.

My other, later, 80's Yanmar doesn't need this to run nice, it runs fine on straight diesel but seems a little quieter and smoother with Power Service.

I agree on the diesel fuel cetane type additives. I forgot about them during my discussion on Seafoam et. al. I also use Power Service in mine.
 
Dennis would it be worthwhile to try an electric inline pump, after the inline filter and before the transfer pump? This would make sure the transfer pump has plenty of fuel at it's inlet. Maybe put a second filter after the electric pump?

Bryce.....I am dyslexic as it gets........I see things backwards so bear with me....Are you saying to:

After the filter coming out of the tank to put in an electric fuel pump, 12V, by actually taking the fuel line coming out of that filter and then to the electric pump and put the output line coming out of the electric fuel pump to the inlet of the fuel injector input????

Basically, bypass the OEM mechanical fuel pump with an electric one, 12V.......

......Something tells me this would be a great test of the fuel pump.....Did I see someplace that there are other lines coming out of the fuel pump that do something else????......

Good Bryce.......How much does one of these outfits typically go for.....Gotta do some research on Amazon....Is there a GPM, gallons per minute, to look for???

Thanks BUD.......God bless....Dennis
 
Mr. Avanti.......

I have used the Cetane with the Lucas pretty religiously with great results. Often this will get me through a whole tank with no problems. Here lately I quit doing this and within a tank or so I have the results I began this thread with.........

Usually I mix 4 or 5 oz of both Lucas and Cetane boost to a new tank.....Honestly, I don't know why I quit other than it was running quite well and not dying very often........Now it is doing the dying every time I run it, even with the Lucas that I put in last night........Tomorrow I will put in some Cetane and see what happens...........

Should I just forget about this Cetane/Lucas business and go for the pump........

lol....it is interesting to see what these additives actually do in my situation...........Thanks so much for the thoughts guys......God bless.....Dennis

Looks like the same type of mechanical fuel pump that was on my 265/283/327 V8's chevs ...........straight in and straight out..........Leave it on the engine and Amazon has a replacement for easily under $20 vs the Messick $109.......

Would you go ahead and get the Kubota replacement or get the electric, 12 volt, and just leave the original in place?????????...............
 
yes . just by pass the factory fuel pump and use a low pressure electric pump. if this is the problem then you will know.
