I have a 290 Enticer - twin 502's with Mayfair external steering - for some reason i keep blowing lines under the dash at the helm -

ANY thought's ?

are the lines blowing or is the fitting coming lose at the hose?

blowing the fittings off the end of the line

prob a restriction dead heading pres,I had trouble with the line at the transom,Mayfair said it was mainly due to Hustler not putting them together right.

i riged up a nitrous presure gage and put in like to read restrictions,the filter that on the 500 efi they said should have lest that 100 psi showing free flowing,Mine showed 150 they said that prob a end of the has was probsticking in the path,it works fine like it is,in picture i was testing the pump

i down loaded a diagram from the Hardin web site, it looks like one of the external lines was on wrong ?

do you think this is my problem?

yes

I'm hoping this solves the problem tonight ...ugh!

Have you ever heard of this before?
