If a replace it with a bigger or smaller one will I have dramas will fuel pressure even though the pumps in my surge are not going to be touched?.....cheers Link to comment Share on other sites More sharing options...

I use a std main tank pump to 5l surge tank and walbro 460 inside that. My car is only 400 hp on e85 but ive never had a problem with the std pump feeding the surge tank enough fuel. just remember the pumps flow is higher as its not under pressure. so although there like 165lph std pumps they would do considerably more at 0psi than 60psi pressure. unless your making bulk power you wont need anything overside in the main tank as you may just end up overheating the fuel.
