What would be the down side to putting an external electric fuel pumps on. My fuel pump in the tank the fittings are so rusted I can not get them to budge in any way but I was also thinking of cutting the lines by the fittings and splicing in some extra gas line and hose clamping on to pump any thoughts would be helpful

Pressure. Once the pressures got over the amount used for carbs, it's hard to put them inline. Especially if you have rubber lines. The suction side of a 50 psi pump will try to collapse the rubber hoses, especially if it's after the filter.

That may be for a d1. I had more experience with a d2 and it runs higher pressures I guess.

It couldn't hurt to try I suppose, I'd probably fix it right, especially if it's one with the cheap pump, no advanced evap.

On my 1996 I soaked them with PB blaster over night and they came apart, but it was a pretty rust free vehicle other than those lines and the screws the held the cover plate on.

Some have had to run new hoses.

What? We routinely run 50+ in LS powered cars. I think I'm at 58lbs. I'm running 35lbs in the rover as is. You run a pre-filter and post.

I stand by what I said. Pushing 50psi of fuel makes more sense than pulling it. That's why every manufacture puts the pump IN the tank.
