I pulled the sending unit and pickup today in my John Deere diesel tractor because the lever sensor was intermittent. I fixed the sender but noticed a broken hose on the bottom of the pick up. The parts book says there is suppose to be a screen on the bottom of that hose. I haven't fished around in the tank yet to find the screen yet. I'll do it tomorrow.
My question is on the hose. What should it be? I see that the external hoses are Goodyear 30R7. I do not know what to go get for a hose that is submerged in diesel fuel 100% of the time. Obviously whatever they used did not last. It was not the Goodyear 30R7. The external tank hoses are in like new shape.

I read the AC Delco write up and the Gates write up. Both recommend the SAE30 R10 hose for submersible in Diesel. Now to find it. I need a whole 3 inches or so.
Thanks or the information.

Ken,
Here's a site; and some good info.
http://autoperformanceengineering.com/html/kits.html
If you need to put a piece of high pressure hose in your fuel tank, be sure it's rated for in-tank use. Your typical parts store high pressure EFI hose is only rated for outside the tank use [SAE J30R9]. That hose will turn to mush in no time. A six-inch piece of 5/16 high-pressure, in-tank hose made to Chrysler specs [not-quite-J30R10 spec] is $3.00.

I'm currently replacing a rusted leaky steel fuel line on my '95 Sonoma. I noticed that the GM "rubber" hoses attached to the 5/16 and 3/8 steel lines have "Fluoroelastomer" marked on them. I believe that type hose would be good for a submersible application. If I needed a short piece, I'd go to a Pick-A-Part and cut off a piece from a '05 and up GM truck. The easiest ones to get would be the ones that come off the gas tank. Very easy to get them if the bed is off and if it's not, they can be reached through the wheel well to cut off a small piece. The lines are about 12" long. My truck is very rusty underneath but the fuel hoses look like new both inside and out.

Mike,
I think if you submerged that hose in 15% ethanol for a while you'd learn
that the flouroelastomer is only the lining -- NOT the external material --
like 30R9, which is specifically not recommended for submersion..
