It takes around 15 minutes to test with video. Chime is lockated under the dash driver side-********* block in fuse box-just take it out-mine's out as it's unberable-I use the socket for power source for my roof lights switch.
If I disable the chime - do I lose the lights-still-on warning?
Depressing the Schrader tells me if fuel has come up. There's a little spurt if it has. Zero today though.
Video is handy for the pinouts for the relay. I'll test the relay as well and jump the pump also. If the relay side is all good but no fuel when jumped I'll go as far back in the wiring as I can access before declaring the pump a goner. If it's goosed then a strong motivation to re-tank both tanks.
Getting parts from the USA is tricky at the moment due to a credit card issue - almost resolved - off for a meeting with the bank shortly to resolve finally.
Testing as outlined is for next week - this week has been exhausting for a number of reasons.
My tank is 100l-didn't see the point in smaller one as I travel to Europe in this truck. Naturaly u can only fill it up to 80%.
You have a heavy right foot!
