I have read a few threads for the lift pump and have yet to see the benefits shared. I assume it is to provide more even fuel pressure in the line? Does it help during cold weather also?
I need to run by the auto parts store today and will take a look at what is available.
Its not gonna make cold weather starting any easier. All the pump does is
keep the fuel supply line under some pressure. Its not a replacement for
the factory suction pump on the engine either.
The factory suction pump has to suck fuel all the way from the tank. If there
is a leak somewhere between the suction pump and the tank, air will get
sucked into the line. This is a bad thing and can cause hard starting and
rough running.
Putting the fuel supply line under some pressure will keep air from getting
sucked in. In the event of a leak, fuel will come out of the leak point rather
than air being sucked in. This makes finding the leak A LOT EASIER.
This is not to say that leaky fuel lines are a common occurance. But should
you have symptoms of air-in-fuel, your gonna have a hell of a time trying
to find out where that air is getting in from.
The most likely leak point is at the fuel filter assembly. The gasket on the
filter is a possible leak point. The fuel heater and temp sensor are possible
leak points too. Especially if an air pocket develops around the fuel heater,
causing it to overheat and melting the housing.
I know, sounds like a lot of doom and gloom, but how does that saying go..?
An ounce of prevention is worth more than a twelve pack of beer???
