The V8 Owners Forum -

my cars fuel pump is dead Just got towed home! It's a rusty lump by the fuel tank, it was a nice diaphragm pump as you could hear it work, no fuel return, it would just fill the two su's up and stall! It is wired theough the oil pressure switch. When the engine was running it would of course keep going!

Any idea what the pressure or the flow rate would have been.

Looking around I see a number of low pressure fuel pumps rated at "150bhp" with specs like:

Pump Part No. 60106 (kit)
12 volt
negative earth
pressure 4.0-6.0 psi
flow 32 U.S. Gllons per hour
dry prime height 0.3 metres
thread size 1/8th nptf
Power Range 150bhp

Are these suitable for a standard tune rover v8?

Standard 3.5 on SU's is around 3.5-4psi. I have a pressure regulator set at 4 with a return to tank, just in case.

Thanks, ended up with a genuine facet red-top and a fuel pressure regulator, eBay 2nd hand but looks new, runs a treat. No tank return and the pump does slow if you run it without the engine running but I guess they are designed to handle it. It's wired through the oil pressure switch anyway so as long as the SU's can burn enough fuel to keep the pump happy I will be OK!

Funnily enough it was a facet I took off, not that you would know the case was very rusted!

I have run a Facet Red Top now for years, originally with a pressure regulator, but ditched the regulator when I realised the carb float valve, along with the long fuel hose run from the tank in the boot, handled the pump's output ok without flooding.

ps. Just FYI, basically there are two types of pump, those designed for engine-bay mounting (known as long-suck - short-blow), and those designed for mounting near the rear tank (short-suck - long-blow). The Facet is the latter, but SU and some others come in both varieties.

Hi, I've inherited an old classic with a top fed fuel tank (think its a replacement out of something) and the flat spots are horrid.
I've changed the distributor cap and rotor arm, checked the coil, leads and compression. All is good.
I put in a new filter (metal one) lower than tank and as near to tank as i could.
THen i removed the old pump and 2nd filter and put on this one from paddocks http://www.paddockspares.com/fuel-pump- ... ctric.html and it didn't run. put the old one that it was built with and it runs.
Dumb Question is: is this because my tank is top fed and the pump only pushes and not sucks/pushes or have i missed something?
I've checked the flow and the pump ticks and it was lower than bottom of tank, etc.
Stupidly, i'm stumped! [/url]
