Fuel Surge Issues?

[No Crust Racing]

What's the logic there? Pump stops pumping? OR that it pumps at low pressure and the motor runs lean? (I run a wideband and have the knock reading on the SAFC as the main reading when driving.

I'd of thought that if a drop in fuel pressure was going to blow my motor up it would have happened already with the few times I've had fuel surge issues and misfired because of it.

In which case I'd do the same thing as I did then, stop driving.

Not disagreeing, just opening up for discussion.

Just thinking, should I also be considering an adjustable regulator or do I just assume the stock one is fine?

I'm also on the fence about whether this Bosch pump will flow enough fuel, I realise the kpa ratings are within the limits I need (supposedly 300kpa base fuel pressure plus another 120 or so to account for boost) but the LPH just looks so low.

Stock reg is fine. Why dont you just buy 044 there cheap enough?

[No Crust Racing]

Because these are cheaper and if it's suitable then why not? Still Bosch.

No point in me having a 300lph pump on a 1.8L with 460cc injectors, unless I actually need it.

Oh and BTW Zebra, confirmed that Walbro is genuine.

Problem being that the size of the body makes it a pain in the arse to get something to mount it with other than ribber p-clamps.

Any issues with mounting the surge tank in this location?

Hole in the spare wheel well for hoses.

The surge tank plate prohibits me putting it in the wheel well without decent modification and new fittings between the pump and surge tank.

Here's my surge tank located in a wagon - so I have had to make a steel cover for it.

My concerns re my location are.

A) Weight distribution
B) proximity to wheel well in the event of an accident.

Cheers for everyone's help, just some wiring left to do.

Do you guys know what the rules are on sealing the boot in? I'm planning on using just an aluminium sheet over the rear firewall, do I need to cover the parcel shelf also as it has those speaker holes. I assume so?
