[Tigers] (Non-Tiger) Fuel pressure falls off with temp?

[Cullen McCann]

Good points Stub&.We checked to make sure the cap was properly ventedb&although nothing changed in that area during the installb&but we havent tried running it without the cap compeletlyb&we'll try that. Specs on the pump are a good idea to checkb&the pressure does not come back with RPM, it stays where it is or continues to fall.

thatbs an ideab&I will check the dims on the pumpb&.its cam accentric ( spell check) drivenb&can't think of any complications thereb&but you knowb&..you have me thinking nowb&

Thank you for the feedback! b&b&..I like how your thinkingb&.

A couple thoughts...



Are you sure the fuel cap is ok?  Have you run it with the cap off?



The pump has all those wonderful specs, but at what RPM?  Do the revs slowly drop as it warms up?  If you rev it does the pressure come back up?



Mechanical pump, right?  Could there be a dimensional issue so that it isn't being properly driven?
