If the seal diameters and depths are the same, it should. For the price, I'd sure try it

 

Good afternoon, sorry to renew such an old post, but maybe someone found a solution for this regulator replacement?
My Hot fuel start system is not working correctly, starting only after second long crank (When hot first crank just cranks but not starts).
I assume its this pressure regulator and it seems to be not available everywhere.

I ended up using a racing variable fuel pressure regulator pointed to the wing of the car. All has been fine since.

 

I've found an OEM regulator on ebay Germany a couple years ago. Although the Aeromotive one Greg in France linked in in his post could almost be mounted in place of the original one.

 

What was your solution? I have the same problem.

Have you tried it ? Because many look the same but the diameters are different and they don't fit.

 

No I haven't tried it but it looks the same.
