What are the differences between fuel hose and water hose? (rubber hoses)

I figuyre fuel hose prevents against petrol deformity/corrosion. Does water hose have any Pros over fuel hose?

Why im asking is i have a length of new fuel hose of the right diameter which im thinking of putting in place of the rubber 'flexi' hose from water pump to head. I obviously dont want to put it there if it cant handle the heat or pressure or somthing like that.


Did i mention that i was tight on money?

EFI hose is SAE30R9. This has a working pressure of 125 psi and minimum burst pressure of 900 psi. The SAE30R7 hose is only rated for 50 psi and a minimum burst pressure of 250 psi. The construction of the two hoses is different and the temperature ratings also vary.


Here is a good spec sheet on different hose types:

That said, I have never had any problems using fuel hose in place of vacuum or heater hose
but would never use anything else for fuel!

thanks for that awdmoke, this hose is 30R7, perhaps it cannot handle the pressure. Ill just buy some water hose.

I use 1/2" water hose. I've found the Made in USA stuff is best. Asian hose is crap. Ditto for fuel hose these days. :wink:
