Think I'm going to replace my fuel pump. Builder of my car warned me that the stock pump in another LS converted car he built was running out of steam at the power level I have. (mid 370's rwhp).

I'm considering either the Bosch HV or the 044 pump. Anyone have any opinions on which to use?

I've read a few install DIY's, if the fuel pump is outside the tank, that means the one you access from inside the hatch is a transfer pump?

TIA!

 

I thought the only fuel related item to access inside the hatch is the fuel level sender?

The fuel pump is attached via rubber hose to the bottom of the tank, passenger side of the car, its concealed under a plastic cover.

I wonder how much sound this rubber absorbs..

 

I'm about to replace the fuel pump as well. Does the rubber cover come off the stock pump and slide onto the new one?

 

No. It is molded on.

 

Oh well. I'm not sure I'd hear the buzzing fuel pump over my exhaust anyway.

 

^^^ Cut the old pump out like I say below, put the new pump in the old rubber mount.

I replaced my stocker with a Walbro GSL-392 off ebay and a 12mm barb adapter. All in all I spent ~$115. The inlet side takes the 12mm barb, the outlet takes the stock check valve. Cut a circle around the side with the electrical connectors on the rubber holder/mount for the old fuel pump, slide the old pump out, slide the new one in, replace and install like stock.

Edit: Just looked over my notes and I was incorrect above about what side to cut. The correct side to cut and slide the old pump out is the one without the electrical connectors. You'll still have to trim around the electrical connectors a little to get the rings to sit down far enough.
