fuel pressure questions
Hi all need some help?
just installed ISSPRO mechanical fuel pressure gauge in my truck. 98.5 24 valve 2500 2wd
it reads 11-12 at idle...
When I drop the hammer the gauge never moves?
Installed in the "hole" closest to the block on the top of the fuel filter. Have a fuel stuber installed then a 1/4 copper compression to isolator valve. Then to the gauge. the line, gauge side of isolator and the gauge itself is filled with the 50/50 blend of antifreeze.
I burped the fuel side and the antifreeze side but still the gauge does not move. tach was at 3200 comp box on 4 smoke level at 4 also running stage 2 injectors and and a very large K&N Filter.
