Rubber Fuel Line Hose at filter OK? - Third Generation F-Body Message Boards

As expected, my fuel filter was a rusted mess when I went to replace it. I ended up cutting the line on either side of it.

With only 9-13 PSI, is it alright to use standard rubber fuel line hose the rest of the summer until I get under there and replace all the lines with original ones?

Were talking about 5-8" max on either side of the filter.

SAE 30R7 is rated up to 50 PSI working fuel pressure (for sizes under 3/8"), but a safer choice would be SAE 30R9 hose good up to 150 PSI.
TBI runs at about 15-20 PSI at filter. Just be aware that it is common to install TPI pumps in place of TBI rated pumps. TPI can push pressure well above 50 PSI when deadheaded.

I’ve had to do this to a few of my cars being in Vermont. Winters suck, anyway, ya just go get the rubber fuel hose that's meant for fuel injection, because it does make a difference. I’ve blown apart regular rubber hose before and it's not fun
