47-55.1 Fuel line routing

[gravely800]

Hi everyone,

Hoping to get some help and pics. I am doing an s-10 swap on my 49 chevy truck. I got a new tank and the lines came from linestogo.com I'm having a difficult time figuring out how these lines are supposed to be routed. The lines that I received don't seem to be bent the way that I think they should but I've searched all over the s-10 forum trying to find how they are routed and haven't found much. I'd love to see how you guys routed and mounted your lines to the frame from the tank. The fuel filter seems cockeyed, not sure how far it should be mounted. Really wishing that I had taken better pics last summer when I was stripping this thing down! Thanks so much for any pics or advice that you guys may have.

Couple more pics. Also wondering how those 1/4 lines run. From tank to engine then back to charcoal box?

I think your stainless braided lines may be the problem, on an s10 with a tbi tank (thats what it looks like you have, steel tank, big vent line) the hardlines run all the way to the tank and only have short pieces of rubber to connect to the tank lines.



also, depending on your year s10, the charcoal canister can be at the front of the truck (under the hood on a 91 for example) or at the rear of the frame (where it looks like yours is)

salvage yards are invaluable for this kind of thing, find your year truck in the yard and crawl all over it. on a couple trucks I just unbolted lines and took them to the counter.

good luck!

Great advice man, thanks. I was thinking the same thing about the braided lines. I forgot to mention that it's a 95 s-10 frame.

the picture I showed is a 91, which the lines run inside the frame and has a charcoal canister in the engine compartment, your 95 is still a TBI but the charcoal canister is in the rear.

I'm gonna check it out tonight. Do you think rubber hose with clamps is adequate? It should give me some flexibility vs the braided hose. I'd like to see some pics of how you guys fastened the fuel lines, and brake lines for that matter, to the frame. I appreciate the help!

is your truck tbi? if you have a high pressure pump you will need high pressure rubber lines, make sure there is a barb on the end to slip the rubber on and clamp past.

[gravely800]

Yes joedoh, it's a tbi. The nuts came on the new sending unit to attach to female fittings on the hoses. I I should be able to just pull them back and slide a short piece of rubber fuel hose over the sending unit lines and clamp them.

When you guys run your lines do you attach those to the inside of your frame? I was going to do that and use rubber insulated clamps with self tapping screws and attach to the frame.

yep thats how I do it, usually the truck comes with plastic isolators, but rubber ones will work. make sure on long runs they dont have the opportunity to rub together
