Well after an afternoon of fun in the sun and cursing the fuel pump housing's mother, I now have a Walbro GSS-340 (255lph HP) fuel pump in my fuel tank. The job was pretty straightforward, except for getting the stock pump out of the casing (what a pain in the butt!).
I used a silicone sleeve made from a silicone hose cut down the side to adapt the smaller Walbro pump diameter to the housing. See the pics below.
Oh yeah, and the best part is the pump is DEAD SILENT! Can't hear a thing! (Okay maybe a LITTLE, but only at idle with a stock exhaust, all the windows rolled up, and the stereo completely shut off. You can hear a very faint high-pitched whine if you listen for it.)

Looks great!!! I glad you said it's quiet because I ordered that exact pump
too. The buzzing of the inline pump in my EIP SLC is really anoying. I'll
be happy to replace both the stock pump and the inline pump with the Walbro.

I picked up the GSS-340 from JD's Performance for $109 plus shipping: http://www.jdsperformance.com/index.asp?initemuid=245&fcmd=item

Oh yeah, and my fuel level sender was acting up BEFORE the install, so I cleaned up the contacts with some electronics cleaner while I had it out. Now it indicates the proper fuel level like a champ. Bonus! http://****************.com/smile/emthup.gif

Marty, is that a high pressure high flow pump? I have heard that some of the 255lph pumps that put out the really high pressure acctually increase your pressure at the fuel rail because the stock FPR can not return enough fuel and it ends up making your car overly rich.

Re: Yet another Walbro in-tank fuel pump install! (VR6Jim)

It's the 255lph high-pressure pump. The only difference between the GSS-307 (255lph pump) and the GSS-340 (255lph high-pressure pump) is that there is a pressure-relief valve in the GSS-307 that starts relieving around 75psi or so, limiting the pumps flow at high pressures. Everything else is the same, including the pressure/flow curves from 0-75psi.
The car's running just fine, and not overly rich.

I am in need of a fuel pump and I am wondering if I should go with a walbro instead of th $300 G60 pump that my car came with. How long did this take you? Nothing else has to be changed like my 4 bar or any fule lines? Where did you get that silicone sleeve?
Any answers would be greatly appriciated!

Good to hear you got it sorted, you have such nice hands btw

Maybe 4-5 hours. It took a while to figure out how to take the fuel pump casing apart without breaking it. If I had to do it again it'd take about an hour and a half.

I can't speak for anything but the VR6 fuel tank setup, but nope, I didn't have to change a single thing. The stock output line slipped right over the Walbro output.

excellent info...now,
was this plug and play, or splice and dice?

other than the silicon hose

Re: Yet another Walbro in-tank fuel pump install! (Marty)

Thanks for the info. I will be doing this soon. http://****************.com/smile/emthup.gif

Plug and play!

I hope the silicone tubing you've used is designed for use with fuel. www.bakerprecision.com makes note of the following regarding their silicone hose: "Note: Silicone hose is NOT compatible with fuel or oil. For applications requiring resistance to fuel and oil contact us for hose with a fluoro - silicone liner."
Don't know if this is true for ALL silicone hose, but it's something to consider.

Most silicones used in automotive applications (like intake hoses) are approved for oil and gasoline. They just add some junk to the polymer "alloy" and you're good to go, so the entire hose is protected, just just some coating.

how much for that pump?

Re: Yet another Walbro in-tank fuel pump install! (kingofA2`s)

Cool, a friend of mine's SLC in tank pump went a few weeks ago. I'm assuming this will work on his almost stock car?
