Does walbro fuel pump change PSI on stock fpr?
will installing a walbro fuel pump change my fuel pressure?
If so, by how much psi & is it safe to run on stock ecu?
I don't think it should since the OEM FPR set's the fuel pressure, but I just wanted to check for those who have this pump.
TIA

https://www.hyundaiaftermarket.org/f...new-fuel-pump/ It seems to depend on the setup, on mine (255lph hp inline with stock fuel pump 1.5 sohc) I had no problem (with the stock fpr), if it's an in-tank replacement it will probably give uncontrollably high fuel pressure with the stock fpr.

Hey hey hey! On topic here people. I'm wondering about this here debate too. I would be replacing an intank would I have to swap lines and such?

Get the 190lph pump. It's good for most turbo setups and won't flow enough to back up the stock FPR at idle. The 255lph pump will flow too much at idle and cause higher pressure. The 190's are also said to be more reliable.
I believe the install was mostly direct. May need another short fuel hose and some zipties to attach it to the housing. That's like $3 of stuff at any auto store.
