Not sure if this belongs here or in the electric section, but anyway, someone should be able to help.
For my custom installation of a high performance engine in my 1982 Mazda RX-7 (still working on that one before starting a self bild car) I need a high-flow fuel pump. I use a anti-surge tank and a SX EFI pump, but a good low pressure pump is needed to prime the system (right now the Mazda pump is used). I can buy several makes overhere, most common being the Facet pumps. However, I was told these aren't the best quality, and I should get a holley. The problem is, holley pumps are less easy to get (I'm living in Belgium) and a good bit more expensive. Since the pump needs to flow a lot of fuel but doesn't need to put out a lot of pressure (it's almost free flowing as all it needs to do is filling the anti-surgetank) I don't need a huge pump. But obviously, I do want it to last.
Any experience with Facet's here? I guess some of you guys are using one, as it's a very common pump.
Am I safe when buying a facet or should I go holley after all?

I would say that Facet pumps are just as good as Holley ones, but.........

if you can get hold of a second hand Bosch high pressure injection pump (which I guess will be much easier in Belgium) then just use that. You must have a return to tank from the surge tank to the main tank anyway, so it doesn't matter that it is a high pressure pump, and these are cheap and flow like crazy, certainly more than a Red Top facet pump.

I'm going to be using a Facet Solid state competition pump to feed a swirl pot/surge tank and injection pump. They seem like good quality to me, and don't really break the bank..

Again, just bear in mind how cheap the injection pumps are at the breakers yard. Just use two of those, one to feed the pot, one from the pot the the engine. Much cheaper than the Facet and more flow!

The problem with EFI pumps is that they are very bad at "sucking" fuel from a tank. They basicly need to be gravity feed, making them unsuitable for my setup.
I also believe they'd be overkill as a prime pump, I don't want pressure in the anti-surge tank and lines as they weren't really designed for it. Plus, if the pump pushes a lot of fuel at high pressure, it'll warm the fuel up. This is already a problem with the SX main pump.

Hi Bart
surely your surge tank must have an overflow /return line to the main tank ? and the volume of the pump will be only relevant if it cant "keep ahead" of the injection pump for the engine . . As for an injection pump heating the fuel I find that a bit unbelievable .

with regaurd to your comment about efi pumps being bad at suck rather than blow I dont know for sure but even if it is the case you will need the pick up in your tank to be at its lowest point any way . How ever as long as you mount the pump as low as practical it should work fine even if your feed fronm the tank comes in from the top because of the syphon effect.

I'll be using Facet pumps in my car. They've never let me down.

As I understand it, Injection pumps are typically

1. Bad at Sucking Fuel up - not normally a huge issue in most cars, just means careful placement is required
   
2. Bad at running dry for any period without seizing
   

I would agree with both statements, but neither are relevant, as the pump should be situated low down anyway, and if the primary pump runs dry, then so will the high pressure injection one so you will just have two broken ones instead of one!

I have to say that I have used a red top facet to feed a swirl pot that then fed a Bosch injection pump myself in the past before, but now would tend to just go for two injection pumps, they are cheap and also totally reliable if fed with clean fuel.

Horses for courses, either way will work, I have given advice based on experience so don't argue, if you don't want to follow it, do what the fcuk you like!!!!!!

One of the reasons I'm looking at a low-pressure pump is that simply want a high flow pump, not really high pressure, but prefer a new pump over a used one. Injection pumps are useally a bit more expensive, and since I don't need one, it seems useless to pay more then necessary.
As for the "running dry", the point is, a non-EFI fuel tank (as is my RX-7 tank) is NOT baffled. In corners the tank pick up might be higher than the fuel due to sloshing. The fuel would then be in one corner, the pick up in the other. I'm not sure if this would be bad enough to damage the pump, but why take a risk if the solution is using a slightly less sensitive carb pump.
