The fuel pump in my car has been playing up recently. Seems to be a heathcotr tradition as a friends fuel pump died on a trip to heathcote.

Anyway, sometimes it just plainly wont go. Turn key to on, no prime. try again same thing, try again, it goes and I can drive all day with no problem.

It did this when I was at Melb Airport - I had no tools with me and no cellphone. A PITA to say the least. Luckily it decided to go.

I swapped all the relays around which made no difference.

I have connected the pump from my EA and everytime it has started. The original one starts most of the time but occasionally doesn't so im 90% sure its the pump.

This is where it gets interesting. The EA pump is a fair bit smaller in size than the V8 one. The silver case is a smaller diameter and is shorter as well although the pumps are both the same length, the ea one has a big plastic peice on the bottom.

Both engines pumps are rated the same - 85l/hour at 250kpa

The ea pump is Walbro and the EB V8 one is a Bosch.

Im wondering if the EA pump is an aftermarket jobbie and will be fine in the V8.

well if they are rated the same and the EA one fits the EB hole, then give it a go. i wouldnt imagine it will do any harm.

PS check that thread in the wanted section about the wiring harness...

Should be fine on a fairly stock V8, although I would just check the AF ratios on a dyno if you have the chance just to make sure. Walbro make the majority of aftermarket and OEM fuel pumps. Also the size isn't an indicator of flow, I just installed a 255l/hr walbro pump in mine and it is tiny compared with the stock V8 one too.
