[jjohn]

Page 14-62 02 service manual 81-370-02057

Specifications



Fuel transfer (lift) pressure with engine running - minimum 10 psi

Fuel transfer (lift) pressure with engine cranking - minimum 7 psi

Fuel pressure drop across filter test ports (? plural) max. 5 psi



Page 14-56 figure # 1 fuel delivery shows two test ports pointer #21 on the injection pump, and the missing one pointer #6 on the firewall side of the fuel filter housing. Probably a carry over from the old days when you got all the parts eh!

jjohn, on my truck (01. 5 manuf'd late '00), the stock banjo bolt on the "in" side of the filter had the same test port as the banjo at the injection pump. So in essence they could check pressure directly from the lift pump w/o having any drop from the filter.



Man I wish I had that snow, I'd bee taking a week off and sled day & night

Thanks for the info Johnny5

After just finishing 4+ hours of snow removal ... . I would be glad to give it to you! I'm not complaining though, we needed this bad.
