RE: Half tank lean
I agree but this forum is full of curious minds and techie people who want to work out every detail. Especially if a wad of cash is spent on a truck to customize it and do it up - why not take care of half tank lean if you are going through all the effort everywhere else.

RE: Half tank lean
On another forum someone said installing an inline fuel filter fixes half tank lean. As it stops the pressure going back or something

RE: Half tank lean
Hello ,
I have tried this Mod on my New Savage X 4.6 RTR but noticed no difference with the Half tank Lean issue...
I have the fuel tube running in frond of the engine and 5" and the exhaust line 13" ... I have to admit that this half tank lean is a major pain!
Please for you advice !!!

RE: Half tank lean
I think fuel line lengthening is a ridiculous idea. You lose pressure this way over any other theoretical benefits.
I bought some ofna primer fuel filters to try out on my savage and CEN 7.7. They have a one way check valve. You put the filter between the exhaust and tank. It allows the tank to be pressurized and not lose pressure backwards through the pressure line. In theory it makes the fuel pressure in the tank more constant.

Me too
Im not even sure this thread is still alive. I recently took my older Savage 4.6 out of 10+ years of storage. After tearing down the engine and carb, I finally got her to run. Problem is.... the Half Tank Lean monster was biting me BAD. It was so bad I didn’t enjoy driving my truck any more. After much MUCH searching I found this thread and decided the shorter lines made the most sense. So yesterday I shortened the fuel line from 11.5 inches to 6.5 inches, I shortened the pressure line by 3 inches and I also rerouted the lines. I also noticed that when I primed the engine by covering the exhaust, the fuel was moving through the line slower than I thought was sufficient. I removed the muffler and cleared out the small hole with a pick (I may have enlarged it by a very small fraction). I just finished my third tank of the day and COULD NOT be happier. Once I get a thermometer I’ll check the temps. But as of right now, shes purring purrrfectly.
