T return fuel line, anyharm?

[seth411]

I found one post but didn't find enough info.

I've T'd my return line right before my primer pump, and back to the tank as to not filter the oil twice, could this do any damage or could i possibly suck fuel from the return line?

I did this to lower the vacuum on the veg fuel filter. I don't notice any difference in driving. I've checked my fuel strainer, lines, and think I know the system, but can only figure that the dent in my gass tank outlet is what causes the restriction. To add: On straight diesel the vacuum is the same as with veg oil and with a new 90t filter. (the vormax heat exchanger has a vacuum gauge)
