I luv this sh*t, the tank fuel pump is designed to pressurise, at 65-80 psi so running at no pressure I suppose it could spin to fast but without looking it up I think it’s supposed to be capable of 200 lpm so it will empty the tank bloody quick. I understand FW but to hurt the hp pump which incidentally has a gauze filter between the low pressure side and high pressure side contamination will have to jump across from the inlet to outlet in the filter housing. I wonder if the filters are in series or parallel, if in series just remove the first one but I would think they are more likely in parallel
The other option is to use a geologist hammer, the spike end then repair the tank lol
The problem is people assume everything is to technical but when pulled apart the guts are the same as 50-60 years ago, it’s only the bolt on electronics, firmware and software that stuffs things
The inlet line to the hp pump is quick release I know because I put a pressure gauge across mine when looking for the fuel rail pressure fault and the diesel mechanic said most problems with diesels is the fuel flow
