after taking a look at where to put an elec. Holley fuel pump, i got a few questions for anyone who runs one: Do you place them in the frame rails? Will the survive under the truck (eg. going through mud, trails, etc.) ? How to plumb them. I don't want to have to run new line all the way up to the engine compartment. Can i splice into the metal line and run a small section of rubber hose? Thanks in advance for any help.
