do you need two high pressure pumps? if one is constantly filling the swirl pot regardless of demand then the other post pot pump is giving all the pressure required when needed with a backup of the 1/1.5lts of fuel in the pot

No you need one high pressure and one low. The Bosch will be my high pressure so I need a low pressure pump too. Does anybody know of one that will fit our tank?

[FLD]

Ideally you should use a high volume, low pressure pump to fill the pot (something like a varley red top??). Then use a high pressure pump for the rail.

I am still using the oem pump in tank but would have thought cliffies replacement unit will be ok

[JimmyJamJerusalem]

I didn't fit the Sytec pump, is it identical in size to the original pump, hence is that why it fits or can pretty much any size pump fit...?

[NickB787]

if it's not working overtime I would have throughout it ok to use

[FLD]

Its pretty much identical in size. You may get a bigger one in but I doubt you could go too much bigger.

[NickB787]

where is the best place for the filter?

-6 AN though
quick look found this, also lovely colour

they do this one http://www.ebay.co.u...1d#ht_624wt_879

but the picture seems to show an -6An from the filter with an adapter on it

Think this could be a winner as the low pressure pump. Does anybody know the size of the Sytec high pressure pump??

This one's Dimensions - Length 130mm, Diameter 37mm

The "Sytec" is a Walbro pump.

My thought was if the rest of the outflow piping from the swirl pot pump was -8AN the -6AN could be restrictive

[JG]

i don't think you need -8 anywhere, -6 is overkill already.

[techieboy]

The whole bloody setup is overkill anyway.

The "Sytec" is a Walbro pump.

Do we know if the low pressure Sytec/Walbro is going to fit though...? The high pressure one we all fit obviously does but I need a low pressure pump to supply the swirl pot. The one in the link above is (Dimensions - Length 130mm, Diameter 37mm), does anybody have the normal Sytec one to hand to see if they are similar in price?

[JimmyJamJerusalem]

For some reason alot of companies spec the Bosch pump with a -8 inlet and -6 outlet

[NickB787]

the sytec unit I have is 84mm x 40mm thats the normal in tank unit it does not have any flow data on it

you're just pretending you don't need to do it.
even though you conceed you might

[JimmyJamJerusalem]

I'm guessing it's to prevent cavitation
