hey guys i just purchased a granatelli fuel pump. opened the box
and its a walbro gss 307.

my question is, all the sites i've seen says for the 96 camaro the number should be gss 340. which is right?

the box says 82-02 f-bodys. if anybody has any info please let me know planning on replacing the pump today.

thanks

 

The 307 is the low pressure version, won't go above 60 or 65 psi safely. The 340 is the high pressure version. They are both 255 lph.

They will both work fine, especially if you are not blown/turbo the low pressure will be fine.

 

funny thing about that.. I bought the "holley" 255lph in tank pump when I converted my car.. open the box and viola a walbro 255.. it actually had etched on it "Walbro 255lph for Holley"

go figure

 

Yup it's all the same.

 

thats what i thought thanks guys. now as for the install where the top of the pump and the top of bucket fit together it is kinda
loose fit what should i use to make it fit better?
thanks scott
