5/16" (8mm) x 10" (250mm) In Tank Submersible Fuel Corrugated Flexible Hose Line for Fuel Pump Assembly E-85 Safe Compatible

ok

Product worked well for my application. I am a Victory Motorcycle Mechanic and used these to rebuild a fuel pump on a 2006 Victory Kingpin. I was able to lightly heat and then cool the lines to create the bends I needed and they held nicely.

I had to replace a deteriorated fuel pump and destroyed fue line eaten by E85 fuel. These two lines are great to have as an extra one may be needed if you an't get the line on the first time! Use a heat gun, but not too much heat or it will melt the line and make it unusable.

Used it as an in-tank return line in our 66 Corvette when adding fuel injection so far so good, no issues, no deterioration. Will buy again if needed for any other project

as the title says, these worked great. used a torch to heat up the tube a bit, and slipped it on over my fuel pump + fuel pump sender. once it's cold, it won't move. I used fuel style hose clamps as added security.

It works well for changing fuel pumps inside a fuel pump module. The old line had to be cut off, because once it’s heated and installed it is a one time use. They give you two in case you mess one up learning. These are 5/16 (8mm)

Deceptive advertising. Picture shows two soft you think you are getting two. You only get one per order.

Does not fit the actual 5/16" line or pump on customers car. These are way to tight. I grabbed a piece of 5/16 rubber line which went on a tight fit as it should. These Boost Monkey lines are well made, but are not true to size, cannot be forced on, and will not soften up any in a boiling water bath
