recommend me a fuel pump
Having a real ball ache trying to figure out an ongoing fueling issue I'm having. Looks more and more like the pump I have (Sierra pattern part)
is the root cause.
Can folks recommend a decent pump for a 5 bar or so (3 bar required, but I have a pressure regulator)? It's on a Vauxhall red top.
Cheers.

Any preference to fitting this horizontal or vertical?

Bosch 044 if electrons are in good supply
Bosch 979 if electrons are less plentiful
Both are entirely adequate for a highly tuned XE.

Great, thanks. It is to replace a £35 pound special which has packed in after a month. It was horizontal. Just checking that is ok for the expensive
replacement. Will mount it lower down to add a bit more gravity to the intake.

Before you buy your new pump it maybe wise to get the existing fuel system sanity checked....

I've checked it back to front, replaced all the rubber hoses, both pre pump and high pressure fuel filters, pump itself, tried 3 different fuel
pressure regulators, bypassed the copper fuel line that goes along the transmission tunnel and none of this prevents my fuel pressure dropping.
Checked voltage to the pump itself and it's good. So my engineering opinion is that I replaced a crap pump with an even crappier one which is
gradually getting worse.
