Fuel flow test.........

So I took a spare length of hose I had laying around and hooked it up directly to the FD line dumping into an empty bucket. The fuel is dribbling out, not consistent and strong like it should be. I don't want to start replacing things arbitrarily, but could this be a pump/filter issue, or even a FD issue?

I put the jumper switch on the fuel pump relay and it starts right up and sounds healthy.

I'll take a look at the filter in a bit here.

Here’s a quick video showing the fuel coming out of the FD line: https://youtu.be/JMnbHg2UDTc


Test the fuel flow rate of the fuel pump after the fuel filter. You should get at least 1 liter per 30 sec.s or 2 liter per min. Do you have a picture of your new CIS gauge kit? Hope you do not have one from HF. What is your system pressure?
