Thanks for your help

what was the angularity of the rear end of tow vehicle ? if the tank is mounted longitudialy (front to back) this may be the cause . however most electric pumps are mounted right on the sending unit . you may have a grounding problem through your hitch . PBN

if it's intermittant like you describe may be the float arm on the sending unit is sticking when the car's rear end is weighed down with the trailer
