The 1994 Volvo regina fuel system is inherently flawed. Of particular concern is failure to keep fuel pressure. Is there a solution to back up the system by adding an additional fuel pump?
Is it feasible to take the Bosch underbelly fuel pump, filter, and fuel check valve and wire
it in in parallel with the in tank fuel pump after removing the existing underbelly filter?
Splicing into the existing hot wire for the in-tank fuel filter and adding a fuze would be
easy. Is it doable? This vehicle is normally aspirated and non-turbo.
