I bought a 1988 toyota , the truck had been set there for years and I finally took the gas tank of so that I could able to replace the fuel pump bracket . I noticed that the steel fuel line was rusted and I want to replace it , so what size of fuel line do I need ? I think the fuel line and brake line are the same size and both of them rusted .

I just did this on mine. I used 3/16 stainless (by the roll) and trust me, you have to get the metric fittings. Stainless is harder to work with but you do it once and that's it unless you make mods. You can get a roll of 3/16 copper nickel that bends easy & flares easy too. I suggest the Eastwood brand flaring tool, but get an HD unit. A whole lot less cussing and wasted material.

Now the fuel lines are larger 5/16. Experience talking; get a roll of -4 braided fuel line from Jegs or Summitracing along with 4 stainless screw clamps, and a bag of hose clamps / mounts to hold it safely out of the way.

Do it once.

Now personally I would do all the brake lines and not take chances. I got lucky mine failed on the lift during bleeding. Saved my bacon failing right then.

Well , I did think about using the rubber hose instead using steal fuel line , but I am kind of worried about the pressure in line . Is the clamp and hose would hold the pressure ?

Yes , I will replace the whole brake line .

I had to replace the fuel lines after I nicked one while replacing the clutch in my 1992 and noticed how thin they all were... On the tank side I used a 8mm nylon to 5/16 compression fitting. This got me to sae fittings. I then used a universal fuel injection filter to replace the stock one. Then to convert back to metric for the fuel rail inlet hose, I had to machine an off the shelf M14 brake fitting to be long enough for the flare to compress (nothing super difficult just hat to relieve the nut portion about 1/8"). On the return side of the system, I used 1/4" line and fuel injection hose. Only cost me about a weekend and $100.

Why bother. I just cut it off with a hacksaw burnished it with a file and put -4 nylon braided fuel line from Summit over it with two screw clamps. Problem solved. Do the same at the front connection and you're back on the road.

Have you tried Autozone or O'Reilly's? Last time I replaced a brake line, I was able to get pre-flared lines with the fittings in various standard lengths. No cutting, no flaring; just a little bending.

Damn it ! I still can't find any metric fitting .

Can you get some from a yard and slip them on new lines?

^^^This! the company that makes them is call American Grease Stick. http://agscompany.com/product-catego...s/poly-armour/ The brake line comes in 3/16" diameter and has m10 inverted flare fitting. I used these to redo the lines on my rear axle.

I can not believe that ! I found them in autozone and advantage auto parts stores ~~~ Thanks guys .
