Pegleg Posted August 17, 2023 Share Posted August 17, 2023 Looking for suggestions for a bar mounted fuel pressure guage. Only needs to read 2psi so 3 or 4 psi max? Quote Link to comment

How about AFR or a boost guage? Certainly either AFR or Boost guage will give more useful info whilst in use! A fuel pressure guage mounted after FPR can be useful initially but most will adjust so that floats don't leak without using a guage. Is this NA or Blown? If the latter, you will require a pump having potential for 120 - 125% minimum pressure to acommodate boost over base pressure don't forget! 1 Quote Link to comment

The Malpassi regulator has a boost reference port. Is it necessary for low boost applications? Quote Link to comment
Gixer1460 Posted August 17, 2023 Share Posted August 17, 2023 Absolutely, as boost is applied to the float bowl and if fuel pressure doesn't track it, you'll run lean! 1 Quote Link to comment
