Thread: Fuel pump for twin caby 3.5l

Facet not available? The spare pump from my 110 that's in my garage must be worth a fortune. I thought it cost over $300 new many years ago!

Come to think of it ....... I'm sure my brother runs one on his 87 RRC

Correct - but only on EFI cars. I had one in my '86 RRC

I once converted a Falcon XF from EFI to carby. I kept the EFI pump but cut the lid off the fuel pressure regulator and installed a light spring in the reg. I ended up with under 4 psi and it worked beautifully. There's no reason you can't use an EFI pump so long as you provide a suitable regulator and return line to the tank. But for a single line to the carby, no way!

I reckon a generic electric fuel pump will do the job : the V8 hardly revs to the moon, so a pump for a 4-cylinder will work in a pinch.

I used an old Mini electric pump on my previous 110 when the old pump died on me: worked quite well until I sold the vehicle.

Mini electric fuel pumps aren't known for their reliability. I have a few.
So when you sold the vehicle, I'm I to assume the pump stopped working well?
The 3.5 V8 does rev quite high (well, higher than a Holden V8). That's the only way to get any power or torque out of it, apparently.
Yep, generic (or universal) pump is the way to go. I can't seem to find any quality ones nowdays. They're all cheap and nasty.
