Fuel hose liner & cooler hose question??
 

I have the intake off for injector replacement and have 2 questions.

1) My new fuel hose by goodyear says 5/16 fuel injection hose but it has a blue liner? For ethanol I suppose? The hose feels cheap and seems to be easy to slide on the fuel lines even with the factory hose clamps on. Anyone have any problems with this hose?

2) In the picture there is a green arrow ponting to a coolant hose. I thought it was a vacuum hose but it seams to lead to the assist start. Can silicone vacuum hose be used/is it compatible with antifreeze?? Jus wonering because the original hose is toast.

I should've known, I got a terrible leak under the manifold. Best I can tell is that at least one fuel hose is leaking.

Problem with using aftermarket hose is that the ID might be the same, but the OD is not large enough for the spring clamps to create the proper sealing pressure.

Something sounds weird even so... make sure it's 5/16 fuelinjection SAE30R9.

If all else fails use high quality screw or t-bolt clamps.

Never had a problem with goodyear hoses.

Worm clamps are your bestest friend. :nod:

Well its my dumbass fault because you are right alexdimen. The wall thickness is different. I was focused on getting the SAE30R9 that I missed the thickness.

I planned on screw/worm clamps but size was either too big or too small around this lame town. I will get some when I go to Daytona for sure.

I had the same problem when I replaced my uppper/lower radiator hoses. They where slightly smaller in OD and they leaked slightly with the stock clamps. Worm clamps did the trick.

Also, how the hell can you not get the right size worm clamps where you live? Worm clamps are so ubiquitous, I don't see how that is possible.

The word of the Day..UBIQUITOUS.
