It's a few inches long. If that seems fine replace the pump. Also if you havnt changed the fuel filter that's on the frame I'd start there I just replaced fuel pump and filter I will check the hose and do a pressure test I guess Link to comment Share on other sites More sharing options...

Make sure whatever hose you use in the tank is rated for submersion. The cheaper line will break down if you get gas on the outside of it. Link to comment Share on other sites More sharing options...
Vandenborg1 Posted October 8, 2019 Share Posted October 8, 2019 So I just did a pressure test finally running 30psi at idle give it any throttle kicks up for a second and drops down to 25 ish then will come up to about 28 and hold till I drop back to idle Link to comment Share on other sites More sharing options...

If it does exactly the same which it shouldn't. Pressure should rise at idle with it unplug. Could be a bad regulator. I would open up her gas bowels and check the pick up line that's after the fuel pump. Also replace the fuel filter. It's like 12 bucks. If all else fails replace the pump with a oem Bosch replacement. Also the sock on the fuel pump inside the tank could be collapsing in as you give it gas. The 30 psi at idle is fine but it should rise not drop... Link to comment Share on other sites More sharing options...

If it's all rusty I would replace. You can get a tank,pump,new straps and lock ring from rock auto in a kit for 190bucks Link to comment Share on other sites More sharing options...

I'm willing to bet it's a aftermarket Chinese pump that's just failing maybe advanced auto car quest junk Link to comment Share on other sites More sharing options...
Vandenborg1 Posted October 8, 2019 Share Posted October 8, 2019 if you give it any throttle it rises for a couple seconds and then drops to 28 or less Insert image from URL Link to comment Share on other sites More sharing options...
Vandenborg1 Posted October 12, 2019 Share Posted October 12, 2019 I have it figured out the balance resistor had gone bad and was dropping the voltage to low therefore not enough fuel was being sent up when running. Voltage should be between 10-14v I was getting 8.9 at best at idle probably worse once it heated up.... Link to comment Share on other sites More sharing options...
