Can anybody reccomend what pressure high volume fuel pump I should be running. I apparently have a ZZR block with a head from a later model engine. That is the green twin cam tear drop that migrated from Melbourne to Adelaide.

I used VL commodore efi pump on my twin cam...... be aware these types of pumps fail almost instantly if no fuel fuel

Thanks Glenn,
Would like to hear other opinions, if not i'll be off to find a VL pump tomorrow.

thats a while ago of course, these days there are probably plenty of similar pumps.

Vl high pressure pump is what i run to,i didnt run a swirl pot on Russel's car either it just gravity feeds and has worked fine. I ran these pumps on a couple of supercharged v6 pajero's they both ran out of puff Around the 200hp on the dyno. Due to fuel pressure and injectors the injectors were upgraded on 1 car and it was a big improvment but the pump could not keep up. These pumps are more than enough and available if needed at most outlets if you need 1 due to a failure. Russels car did fail 1 when it was 1st on the road but has done many ks since.

I used the VL pressure pump Bosch 070 pump should be sufficient or if high horse power with turbo use an Bosch 044 pump. the other alternative is a Walbro I thinks its called is also a very good pump and you can find this out quite easily on the net.

My LS1 powered EJ has both the 070 as a suck pump for the surge tank and an 044 for the main pressure pump but that for a V8.

I hope that helps?

When i did my EFI GT way, way back, i only used the one pump also. I fitted it up behind the rh rear wheel area, adjacent to the tank, low down. Make sure you use rubber mounts also. I fitted a return line into the tank for the fuel but don't recall now where i fitted that. Somewhere above the outlet pipe i think near top of the tank.
