Engine/Transmission (1998.5 - 2002) another fuel pressure question

[gottorq33]

noticed since getting warmer pressure seems to have dropped 1 psi or so at idle now at 19psi instead of 20psi. and at WOT I can get it down to about 10 see mods in profile. Would warmer temps lower pressure due to easier flow??? Also noticed on truck compass when temp is below low 30"s truck bucks a little during hard accelaration but when warm its fine could it be EDM'S

Your filter could be getting a little clogged as well.

yes higher temps will cause the pressure to be lower--chris
