Changing fuel filters

[flyboytravel]

I have a Cummins ISC 8.3 in my class A. How can I stop the fuel flow while I'm changing the fuel filters?

Thanks

Low fuel. park downhill or level nose down to limits. Not really that much loss even when level.

Thanks. I have read where pinching the plastic fuel line works. Is that advisable?

There should be a shut off valve close by to the filter

Whether there is a shut-off valve depends on the chassis year and model. Many do NOT have them.

If the fuel line is a flexible hose, a common mechanic trick is to pinch-clamp it with Vise Grip pliers. The chassis or engine manufacturer probably won't recommend that because it is possible to damage a hose that way, but it is a common technique anyway. Just don't get carried away!

If it's plastic...NO! It will cause damage to the line

If it's rubber....maybe if you're careful to not cut the rubber or damage the inside.
