Greetings
I am looking for advice on purchasing a manual fuel regulator with a built-in pressure gauge, I want to keep an eye on the fuel pressure and be able to adjust it accordingly, of course by modifying the pump wiring and a new pump if necessary.

Unless you’re going for big power, I wouldn’t bother

Buy an uprated walbro pump and that’ll be all you need to do

Cheers Jamie

no sure, I'm under 300hp, maybe 280, I would like to make these changes just to have a safe supply and not run lean, (and also clear that if you run lean there could be other causes) I think it's a psychological problem and also a mania to buy more and more things for the coupe.
Do you have a link for the pump? thanks.

will this be okay?

Yeh, I think that’s the correct one

FYI, I run similar power and have no issues with fuel pressure, albeit I’m using vxr injectors

Cheers Jamie

could you give me some info on those injectors?
I'm always hungry for knowledge when it comes to the coupe, and with injectors you know when the originals die they're not easy to find.
Thanks.

I do have 2 sets of OE injectors for sale, I have tested the resistance on them all

But if you want something else, then the Vauxhall vxr injectors are a more modern alternative

They will fuel a coupe to over 400bhp, but they need a custom map,I went to flea for this

Cheers Jamie

you are definitely talking about 0280156280.

Greetings,
could someone confirm that the pump in the link above is the correct one? It would be a Walbro GSS340. Kit: ITP258
Thanks

The GSS340 / 41 / 42 appear to be identical except for the intake port where the bag filter attaches.

just to be sure
