Relatively inexpensive thing to do..this is after 2 years of running with the filter (summer months), filter is before the fuel pump. Should get the tank baked and lined for sure. I think stock pumps come with filters, not 100% on that, but if you are having fuel issues maybe take a look!



Compared to new

 

I did that on my 78 280Z before I dropped the tank and boiled Lined it but still I have a filter before the pump.

 

What filter are you using, this one is 40 micron I think, but a 100 would be less restrictive, but so much junk in there , walbro working overtime lol

 

I am using the same filter that you have....
I think they are good clear filters.....

 

Thanks for the recommendation Skully.

You've got great timing as my project has reached the "fuel system" stage.
Next up is vapor recovery, gas tank and flexible fuel line installation.

I pulled the low pressure electric pump off the car as I changed my flat-tops for round-tops. According to Bruce at Z-Therapy, the mechanical one will be just fine with my configuration. Still considering filters before and after the mechanical pump. Any thoughts on this or recommendations?

BTW, been out of town for three weeks on holiday (hence the lack of posts). The last four days we spent at wifey's BFF's home in California. Her husband purchased a used car for their kids while we were there and I got to spend a couple of days with the husband going over it, examining, cleaning, servicing, fixing and so on. After missing my own project for over a month from a huge honey-do list and the holiday, this was great fun and good therapy too.

 

I am not sure about a prefilter on a mechanical fuel pump, have never seen one so I couldn't tell you good sir. It might be too much obstruction for it.

 

Thanks for the pics skully, this is on my list to do as well (already have the filter). I'm Not exactly sure where to put it on my 76 280z... The PO has 1/2" line running from the tank to the pump, which looks like it was recently replaced. I thought that line was supposed to be 3/8", so I may need to get a different filter. Mine is the fram G3 I think.

 

Thanks Skully, I will check my in line fuel filter as well

 

The proper line from the tank is actually 11mm. I tried to use 1/2 but it was too big, and the clamp would squeeze the hose weird and It was always slightly leaking. I have a machined reducer, 11mm on one side, 3/8 on the other as the filter, and my fuel pump use 3/8 for suction. This way there is no mixing and matching, goes from 11mm tank to the reducer to the 3/8 G3 to the pump.
