It will be fine.
The real question is whether the existing wiring is fat enough for the current drawn by the bigger pump. The 342 is not that hungry, but it will be well worth pointing an IR pyrometer, or even better, a thermal camera, at the pump hat wiring when it is running, just to make sure. Or, you know, just touch it to see how hot it is.
Hi guys,
Sorry to revive such an old post!
The fuel pump in my M35 has finally given up, the car has been sitting for 3 years so I'm not surprised. I bought a Walbro GSS342 of Scotty some time ago, so I'll throw that one in. My question is, if my car has no performance mods at all, do I need really to mod the wiring to supply constant 12V? or will the new pump be just fine at the reduced voltage at idle?
Thanks guys..
