Rough at idle with new fuel pump...
1989 f150 4.9L. Replaced electric inline fuel pump with a much quieter Bosch. Rough idle right after start. What do I need to check. Thanks

I'm new single tank, pump and filter. Do I check the pressure at the "pressure test point" and if so what is it supposed to be? Have had several 300's but this is my first EFI.

For the 4.9. It should be 50-60psi at pressure test point
