Listen up,, if u have a detroit u need this, or when ever u change fuel filters,, u can use the primer pump on filter block,, after 300 pumps, yule buy one. Awesome product, just put 100 psi in tank hook up to truck ck fitting open valve u can actually hear it pushing thru block, start truck turn off valve on hose unhook fitting, ur good to go. GET ONE U WON'T BE DISAPPOINTED.

Pressure relief is too light.
The pressure relief valve is too light, you should have 110 psi to the fuel system & the tank leaks are around the check valve this tank should not leak at all.

Worth the money
We purchased this for our shop and it works great. We have used it maybe 20 time and it has not let us down. The pump handle is ok but has a place to use an air chuck, much faster.
