Lift pump PSI?

[Drago]

I know I saw it somewhere, I put a gauge on the drain side of the fuel manager and I get 3-4 psi while running, that seems a little low, what should I be getting?

new OEM run around 6 psi some higher some lower best test is at WOT should never go to zero

9-10 psi and enough volume makes a big difference.

The reason I'm asking is the truck stopped cold and the culprit was an added inline fuel filter was clogged, remember my tank is a 35 gal chemical tank bolted to the bed so it sits higher than the original tank. after I replaced the filter and primed the fuel manager it fired right up and I check the pressure as I said in the other post. I'm going to check with a new gauge to make sure because this gauge has been banging around my tool box for at least 15 years.

At WOT or idling? If idling, that's too low.

What type of inline filter are you using?

I had one of these laying around http://www.napaonline.com/Catalog/CatalogItemDetail.aspx/Fuel-Filter-Gold-/_/R-FIL3129_0331343037 I didn't have a tank sock. I'm guessing it either doesn't like BioD or my BioD is suspect. The Fuel manager filter looks like I just put it in.

July 10 is when I put my hillbilly tank in and I put the 3129 filter in at the same time instead of a sock

I think it may be to fine and to small? 20-30 micron is about right as a first stage.

then I'll have to pull out the 5micron I got from work, it was designed for veggie based ink so I thought it would work good with Bio D

It would probably be good to go on the pressure side of LP. Most LPs dont want to suck as good as they blow.
