Had to get a tow home last night after the Holley Hi-volume mechanical fuel pump decided to fall apart internally. Pretty annoyed because that's the second one I've had that's done the same thing.
Figure the best thing to do is fit an electric pump, but had resisted this because apart from aforementioned reliability problem, the Holley Hi-volume mechanical delivered heaps of pressure without the hassles of wiring in an electric.
So my questions are, does anyone know of a hi-volume mechanical pump (other than Holley) to suit a Cleveland? Edelbrock have some great ones but alas only for Windsors...
If I go the electric, my choice would be a Holley Blue. I see there are issues with noise so rubber mounting is the way to go. But my question is, do these need to run a return line?
No, no return line is needed they run at much less presure but hi volume..There is no difference with electric pumps from motor to motor.. W or Cle Evo 7 except for demand...Better fitted close to tank,they push much better than suck...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

A Mallory 140 will do the trick. It's a much better designed pump than the holley. I run a Mallory 140 myself.
Remember to run it on a relay and also wire in a gas safety switch. The reason for the safety switch is so if the engines not running (no pulse to the safety switch), the pump won't keep pumping. Also a good thing if your even in an accident. A Malloy 140 fills a 5lt can in about 30-60sec. Imagine that being pumped onto the road in an accident. Extremely dangerous.
Holley Blue's are fine for up to around a 220rwkw clevo.
Mallory's are a good unit as Brenx said. Quieter too.
Similar to what Brenx said, wire the fuel pump so when the engine isn't running, the fuel pump cuts.
I've got mine going from a relay off the alternator exciter. Then a button to prime in the morning.
Cheers for that.. Why do you say only for upto 220 rear kw?. Thought they were a 14psi and high volume pump. Pretty sure I've seen them on drag cars doing 8 & 9 sec times....
Reckon I've got an honest 470+HP at the flywheel - motor was on an engine dyno 3 years ago and netted 402HP before doing the recent stroker conversion, more head work and the bigger solid cam, duuno what that would be at the rear wheels..
