Fuel pump question
Posted: Thu Dec 03, 2009 7:37 am
I just got a really nice fuel pump from eBay, but I don't know a lot about it. The price was right, so I thought it was worth a shot.
It's an aftermarket replacement for many makes and models of cars, specifically Celicas, 4Runners, and Camrys. It's mostly for model years before 2001.
The cross reference part numbers are:
AIRTEX: E2157
BOSCH:
0580453407,0580453449,0580453483,
0580453411,0580453412,0580453455,
0580453460,0580453461,0580453465,
0580453408,0580453417,
0580453453,0580453483
Anyone know if this pump has a built in pressure regulator? I tend to doubt it, but it has an obvious inlet port on the top (fits a square 2" x 2" fuel strainer) and another small hole. The output port is on the bottom. Could the small hole be a return? If the small hole was not there, I would assume the pressure regulator was external, but I am told it's a 3 bar pump, which is almost exactly 43.5 psi.
I have a Suzuki GSXR pump that has a built in regulator, but it's much larger. This is for a motorcycle application, so this smaller pump is nearly ideal. A built in regulator would be icing on the cake.
Any information on this pump or car pumps in general would be appreciated.
