Well I orderd some more parts. This year I plan on replacing fuel lines and trying to do a in tank and external pump set up. So I can cruse without the noise. I am just not sure how it will effect the Fule pressure
Well, changing the set up but not the thread. So far I have enjoyed e85, there have been a few hang ups. It's importan to keep your fuel system clean. I have found Teflon lines that should work with the fittings that I have. With the new hoses and filters the fuel system should be done. There is one more thing I am going to try, running a intank double pumper in parallel with external pump. So I can cruse with out the noise. Along with the fuel system, I am upgrading to a 4.1 block, a 72 turbo, champion heads and intake, roller cam, and finall a scanmaster "I might not pop another head gasket". Thinking wideban o2, 9" rearend, and paint soon.
This is how I made room for the oil drain back in the 4.1 This is finished product. Do not drill the 1 5/8 hole all the way it will be too big!!!! Tap size 1/2-14 NPT and drill is 45/64
This is a super late response, but what you are saying about the 'black gunk' is true. This issue has been traced back to what is called "drag line reducer". http://en.wikipedia.org/wiki/Drag_reducing_agent This 'stuff' is nasty, and, it is used in different parts of the country, and usually in low-grade gasoline loaded in to railcars. Low-grade gasoline hauled via semis are not seeing the same problem.
I also had a lot of stuff in the secondary fuel filter. I decided to change the fuel lines to Teflon lined. more to follow
I, too, have seen this stuff get past filters. Also, you're 100% correct in that this 'stuff' will go back in to solution with regular gasoline. It will disappear, just as it did when you cleaned your injectors with gasoline. Edit: I see no issue with upgrading your fuel lines - makes sense to me.
Well parts are on the way. I have been working on getting this 4.1 put togeather. There were a few problems, but I think they have been ironed out. I recived a few emails informing me that the parts are on the way cometic head gaskets, cam, new fuel lines, and a bunch of other parts. The ups Gus will be busy the next few days. I will post some pictures, I have to give a shout out to Fragola performance for the Fule lines they really took care of me. Turbo farm also was a big help Prasad did every thing in his power to help me with the parts I orderd from him. Thanks
