hey everyone

thinking my fuel pump might be on its way out but havnt tested it yet, just wondering if anyone around has replaced/upgraded pumps and pressure regulators and the like. are their any nasties to look out for when getting a pump and reg. cheers everyone

Madcat was successful in upgrading his pump with a Walbro 255 ltr/hr:

Yep, It swapped in nice and clean. The parts bag said it was for an 89-94 Nissan 240SX.

When you go to pull the pump out of the tank the pump assembly needs to be tilted to the side and twisted clockwise ( i think

) and counter-clockwise to slide it back in.

what sort of regs are good, from what i have seen so far there is a fair price difference, i guess ill do some web research. still on a mission for the pump havnt had much chance to ask round yet.

cheers again

I hear a VL turbo fuel pump does the job...

I wouldnt bother with a VLT pump. Originally issued from factory, the VLT and VL N/A pumps were different. Bosch now only makes one that caters for both.

If you do your research you can get the Bosch O44/040 600hp pumps [ones external, ones to suit intank pick up like 200sx, i forget which is which] for $200 brand new.
