fuel pressure dropping over time

RRR, worried that someone may know more than you????
If I wanted to be an A-hole pal, there are PLENTY of your posts that I could comment on that are full of BS. Would you like some examples?
As far as helping the OP, I have stated that I believe his return line is too small, in numerous posts, another BS post of yours that I am not trying to solve the OPs problem.

Nope. Never been a problem for me. In fact, if you look through my posts, you'll see I disclaim what little knowledge I have all the time. What I know will fit on half the head of a pin, maybe less. I say it a lot.

As for the other, it's all a matter of opinion.
