Carter electric fuel pump

[scott nutter1]

After reading Bobs post on Chinese fuel pumps, I did a little research.
The pump that seems the most popular for our Gmc's are the Carter p4070's. According to Amazon they are made in china?! At $53 for pump.
Now Amazon also has a Carter p4389 electric fuel pump for $54. Amazon says it's made in the USA! The deminshions are about the same, 6psi (4070 is 3-6
psi), and made for marine use.
Does anyone have any history with the p4389? Recommendations? Our a fresh set of eyes to double check my findings.
My application would be to hook it up the the aux fuel switch to help prevent vapor lock.
Thank, Scott.

Mr. Gasket and its clone. A bit cheaper, and a built in check valve. Just don't use the supplied filter, use the Wix sub. It's now out in a house
branded version for a few dollars less as well.

I usually install the 4070 with a by-pass hose and include a check valve in
the by-pass. The thinking here is that the 4070, due to it's internal
valving, is a bit restrictive, (a couple of psi worth), and the by-pass
hose helps with that pressure drop when the pump is not running. Just what
I do.

My experience with the Carter pump is that it is very restrictive when one
tries to pull fuel through the pump as it is vain driven. I have been using
that style pump since 1995.

I installed a P4070 once without the bypass check valve and it did not go well. It would run out of gas in the carb when I accelerated heavily and the
electric pump was turned off. I added a check valve bypass and took care of the problem.

Jim K. at Applied GMC has everything that you need in one kit. He has, or at least had, one of them ready to go on his table at the GMCMI rally
yesterday.

Both the Carter and the MR Gasket pumps are rotary vane type. Both work well. The Carter makes more noise, but only marginally so, and at the back
of the copach you won't notice it. In thwe ratrod pickup, I notice it.
