Paul Hig Posted August 17, 2023 Report Share Posted August 17, 2023 I'm changing from a Lucas pump to a Bosch set up. Just trying to gauge opinion on whether or not a pre filter is required. Some say they restrict flow, others say that they are essential as stop debris from tank getting to pump. TR6 (CP) with original tank Quote Link to post Share on other sites
kcsun Posted August 17, 2023 Report Share Posted August 17, 2023 I would deffo fit a pre-filter kc Quote Link to post Share on other sites
Andy Moltu Posted August 17, 2023 Report Share Posted August 17, 2023 If you fit a pre filter make sure it has decent sized pipework and is a coarse mesh. It's job is to protect the pump from coarse debris and swarf. The post filter deals withe fine stuff that damages the MU and clogs injectors. Avoid the restrictive glass pre filter that has quite small internal pipework. Once sold by an expert of yester year who also sold a big outlet for the tank. The latter was a good thing, the filter completely negated it. Quote Link to post Share on other sites

Steve-B Posted August 17, 2023 Report Share Posted August 17, 2023 (edited) Absolutely you should go for a pre-filter no question as well as installing a new PRV and if you don't have it, add in a pump relay. We had out tank modified to add a bigger bore outlet to the pre-filter, which helps I'm told with overall flow. Getting a pre-filter which has a removable filter elements helps as you can clear it out. Here's a picture of our installation of Bosch pump and pre-filter: Edited August 17, 2023 by Steve-B Quote Link to post Share on other sites
