It was kinda on the chilly side here last week, and I am running about fifty/fifty blend of #1 and #2. I previous years I just ran additive. I ma noticing a lot more noise from the injectors and fuel lines, etc... The question I have for any of you.... Is it normal for the fuel system to run louder under these conditions?

FYI. I did put a new fuel filter in it last week, and I ran fuel into the filter with the lift pump until I got fuel out of the top ports on the filter canister, but I did not bleed the line going to the vp44 from the filter. It started and ran just fine.

 

mine is noisier in the winter using winter blend, also my mileage drops a little. so i try to use straight # 2, add some 2 stroke outboard motor oil to your fuel and it should help

 

Mine is also noiser when it gets cold and I switch over to 50/50 mix or just straight #1. A quart of 2 cycle oil like 'Johnh' stated will help quiet things down. I think it also help the VP44 in the lube department.... But it sounds normal to me....

 

Thanks!! Seems like a good idea... I will try some 2 cycle oil tomorrow... I topped off the tank with #2 today, but I am sure it is still a blend. It does seem like it has let up a little. It kind of comes and goes. Actually it seems more prevalent when the engine is warmed up. A friend I talked to today (he has had a lot of different diesels from heavy equipment to semi tractors to pickups) said it may be time for injectors. I guess with 240k (I have had the truck since 93k) maybe it is time to consider that prospect too.
