Last friday after work I go to pull out on the highway and she sputters once and dies. Try to restart and it won't say a word. Nose was kinda hanging out into the road so a guy stopped to help me push it back. Pop the hood, no fuel pressure.
I crawl under it and I can hear the pump running but it sounds like the clutch is pushed in. Real high pitched like it isn't doing anything. I thump the tank and get it to change pitch for a fraction of a second. I fiddle with the connector on the top of the pump to no effect hoping it is a lose connection. No dice. So I goes back to thumping. Eventually it sounds like the clutch gets let out, the little motor pulls down and sounds like it is doing something. Truck fires right up and drives 7 miles back home without missing a beat.
Ok, aside from not having to haul it home I don't like that.
So I snag a red Holley pump from Speedway. They were about the cheapest and being out of Lincoln 9 times out of 10 I get it next day, and this time was no exception.
So I get to thinking I can hopefully just use one of the holes from my Mr Gasket fuel pump days until I peek under there and get reminded that my rockslider covers the holes. Wait a minute... sure enough the bolts on my slider mounting pad are the same spacing as the mount for the fuel pump. So I hogged out the holes a little with the die grinder and it slipped right on. Really fits in there nice.
I fires it up and I have 7psi to the carb (2yo in tank pump could only ever manage 3psi)
I check for leaks and decide to circle the section and see how it runs out.
Long story short I don't think it has ever ran so good.
Pre 5 speed it was close, something must have happened to the Mr Gasket pump then, it dropped from 6psi to 3psi while the truck was down for several months.
POS (bolded for extra emphasis) carquest in tank pump must have been junk out of the box because it did the same exact thing as the Mr Gasket which at the time made me question if the Mr Gasket was actually bad and if I had a problem with either the carb or driveline.
These stupid pumps have had me chasing my tail for years...
Now I do need to reset my carb, it runs a little rich... but holy crap when we get into the secondaries.
