The same pump
for gas or diesel
, they are pressure limiterd so a regulator
is not needed, wire to ignition circuit - but - pump
should be on the engine side of the filter so it may not help for your stated purpose. How about a second ffilter on a manifold? Racor
makes one - allows you to switch to spare filter while the engine is running, has a vacuum guage to tell you when filter is going bad. Expensive but works.
