Fuel pump dilemma

Postby InitialB » Mon Jan 05, 2015 8:28 pm

So here's my dilemma.. I'm looking for an external fuel pump for my stock 20v BT'd 86 and I'm having quite a difficult time... I've heard that you should run between 85 and 115LPH but I can't find anything that uses AN fittings. Is there such a pump or am I going to have to have a custom one made (IF THAT'S EVEN POSSIBLE!!!)?

So far the lowest LPH i've found with AN capabilities was 155LPH but I don't know if that will work properly or not..

High volume doesn't matter as your stock fuel pressure regulator will limit pressure and if you're efi system is working correctly the ecu will adjust the mixture.

If you had a turbo car with big injectors then volume becomes an issue.

Long grain- you can't adjust volume with an adjustable fuel pressure regulator, it adjust pressure only.

Personally I would go with a Walbro 190 or other similar common size.
You don't want to go much bigger than that on the stock FPR but the 190 will be fine.
