Well, I don't know how the pulling issue is any worse when the factory mechanical pump is rated in psi the same if not 1 psi less even than my FACET 4-7 psi for fuel pressure. I did not buy this truck for cross country pulling or for telling my buddies how much power it has. I did just pull about 9,000#'s roughly 20 miles. It was not like driving a new twin turbo'd power stroke. I was able to keep it at 55mph except up a steep hill where I would down shift to 4th gear to keep my RPM's at 2000 and 45 mph. I use this truck for around my acreage, hauling firewood, and driving 10 miles and back to my job. It is not fast, it starts good now, and I am slowly but surely widdling away at the undisclosed (previously owner known) issues I have inherited. It smokes, it grumbles, it has a front wheel that leans inward on the passenger side. It has an issue with a poor connection between the alternator and the plug that goes on the top that allows for charging. I get out, unplug it and plug it back on, and it seems to fix it every time. Probably a loose connection. But, you know what, I will eventually get tired if it doing this and I will do something permanent about it. When this FACET PUMP goes bad, I will buy the HOLLEY Red Pump maybe. We'll see. Thanks for the advice!
