>    I have been using a fuel pump for one of the Ford Bronco/Ranger
>vehicles that has a Bosch look-alike fuel injection system much like our
>Vanagons. The NAPA part # is 2P74028,  and the price is around $60.00.

I looked this up on the NAPA site and the very brief specs say it is 30-40
GPH and the pressure is 4-6

I then checked on an 89 Bronco with 2.9l and the only  ones I found were
the in-tank variety, but they were rated at a pressure of 40

Looking up the pump for a Vanagon,  got several choices, all of which were
in the 30-40 GPH range, but the pressure varied from 2.5-4.5 all the way
up to 73, which is certainly higher than most pumps I came across for a
variety of  vehicles. Do all Vanangon pumps need that much pressure?

I also came across a "universal" pump listed under Vanagon, that is not
the cylinder shape of our pumps, but it was an odd looking square part.
The number is  BK 6101051 rated at 30 GPH and 2.5 - 4.5 pressure, and only
$35.....

Now, I am not about to use this on my van as the full time pump, but what
about having it as a spare? Does a pressure  rating of 2.5-4.5 fit any
minimum spec for the vanagon?

The mount is totally different, but a little work up front with some
pre-drilled holes, would allow it to be hung down there in the event of an
emergency.

Anyway, why the difference in pressure specs? Does it really matter, and
given the proper inlet and outlet sizes, wouldn't something like this
strange looking pump be a good spare? For $35, I would carry one of those
around with me just in case.
