fuel line clamps

[Desertstorm]

I had a leak at the fuel pump on my 86 K20. Pump has a supply line and a return line at the bottom, the leak was at the supply line. I am currently using spring clamps. I removed the line and cut off about an inch of line and reinstalled with a new spring clamp, all is good. Question, are spring clamps acceptable? or should I replace with worm gear clamps?

No issue with properly fitting spring clamps IMO. They are widely used in OE applications for low pressure hose connections like carb fuel lines and coolant lines.
Only time they don’t work well IMO is if the rubber hose is older and hardened or taken a set from being clamped previously. Thats when you need the addl clamping force of a worn gear clamp.

I’ve come to really like Corbin/spring/constant tension style hose clamps.

Just make sure they are appropriately sized for the hose/bart and should be good to go.

Nice thing about spring clamps is they are constant tension,like serpentine belt tensioners. Years ago it was common to have to tweak a clamp, tension a belt etc. Because of 6 months of use and a bunch of heat cycles

Pumps for carbureted fuel systems are only 5psi-ish give or take (between 4-8lbs typcially). A good shoe strig will probably seal 5lbs of pressure. Spring clamps are pretty much industry standard for the the past 20 years +

The feed and return are zero PSI.. feed should actually be a vacuum most of the time. The only line on the pump that sees pressure is the outlet to the carb itself, and that is a solid metal line with a flare and tube nut.

Thanks for all the feedback. I was pretty sure that spring clamps would be alright but wanted to check with the forum, Thanks again!
