Just been on here about my situation. My 87 4.3L "MCM175" engine has a electric fuel pump installed.

Don't think it's original. But, The craft also has installed in it a RACOR water/fuel seperator in addition to the Quicksilver mounted on-engine water/fuel filter.

Can a mechanical pump draw through those 2 units OK and still deliver the 5 PSI to the carb?

OR, is this the reason the PO switched to a electric pump? Not sure if the RACOR system is factory.

Still trying to un-do all the PO's DOING!

Thanks.

Ayuh,... I thought this is what We were talkin' about in your Other thread,..??

2 filters ain't a Problem in itself,....
But I have no idea why you have 2,.. 1, kept Clean is more than sufficent...

My guess is, the block has been replaced with a newer 1, without a fuelpump boss....
And,..
All the work was done by a Real Hack...
